Just purchased 2019 macan and trying to solve issue and have been playing hot potato between dealership and porche customer service on who and how to fix.

To further troubleshoot I ask a favor🙂...can someone use their car nav.... need someone with 2019 or newer PCM for apples to apples comparison...... and then their phone nav ( preferably Google maps) and route from same start to same destination and see if routes match or if phones nav consistently gives much quicker routes?

I have tested this on multiple trips where I'm going form my local state to location in a another state ( i.e Atlanta to North Carolina) etc.

Initial scenario based on recent road trip....Phone gives me a route through South Carolina that makes total trip 4:40 long verse car gives quickest route as 5:42 min long and does not route me through South Carolina at all. The reason I bring this up is GA and NC have 2021 in the naming convention in database tables and originally said 2018. They appear to have updated online through internet through nav+ package. All other states still say 2018 including South Carolina.

In speaking with Porsche reps their saying that doesn't even matter if you have nav+ package.... only if you don't because they are static map updates that would require updates via dealership.... but nav plus is direct connection so its not referencing those tables. Not sure which is true but possibly if it is referencing 2018 SC maps the road it's taking me to get to end destination in North Carolina wasn't their in 2018 and why it's not an option🤔

so everyone I have spoken to agrees they should match....car nav and phone nav because both powered by Google. But porche customer service says dealership to perform PCM update and dealerhsip says dont waste you time coming in, nothing we can do for you. If you car is correctly connected to Porsche connect which they have validated then they just display in car what porche connect sends and it's a Porsche connect issue.

I feel like I understand the the tech better than they do now but unfortunately not how to fix it.

Thanks in advance for any kind person willing to help me troubleshoot my theory.

Lol yeh I can use any app via the phone and have audio via bluetooth but that limits my from using in car capabilities that I really wanted. I truly believe the database tables need to be updated regardless than I'm told otherwise.

already has carplay. I am just the wierd porsche owner with an iphone:)...... i geuss based on them stating 90% of NA customer have Iphones which is why they dont allow android auto.

was iphone forever and recently switched to android. Cant go back to iphone now. to much other stuff, home automation etc all tied to google at this point. so I can use carplay when my wife is in car but not regular basis. Also lots of our roadtrips go thorugh mt towns with deadzones which is why i wanted to use in car nav and also be able to leverage the other nav screen in the driving council.

heard word from dealership this morning their escalting to try and find fix becuase they agree somethign is not right. fngers crossed. spent a ton of money on this car and annoyed when things dont work as i know they should.

Op -- You post sounds like such stress that I feel compelled to comment . I don't have any of it . I have two cars with all the Porsche gadgetry that I not only never use I would not even know how . I dont even care that I don't know . I just use my iPhone to talk (which I prefer not to do most of the time) and sat radio . I dont even want to pick my music . Let them pick it and if not happy I change the channel . If still not happy I turn it off or check the news sometimes . I have ACC and dont use it . I have used Nav once time in. my life back in 2003 and hated it . I am one of those guys who never asks directions . I look at home if going somewhere I dont know via google directions . If all, else fails I get lost and it becomes entertainment . I may ask someone but usually figure it out .

The above is old school . I buy a Porsche because to me its about driving . I hardly even drive the Macan because even being a great SUV isn't enough . I DD my 911.

You have this really nice new car and its sad to see that you are not enjoying it . I tell people all the time who love tech ... buy a Japanese car . My wife's adult son has better tech in his new Honda at a fraction of the cost to have it . Porsche can not do this. They are like a football player trying too figure skate -- great athletes but wrong sport .

just try it .. turn f the stuff entirely and just connect with the car . It brings me. a smile every time.

Good luck.

haha my wife says the same thing. at the end of the day i agree with you 100% it was all about the driving aspect that i bought the car for and most imporantant. but at the same time i bought expensive car and believe what i am trying to fix is achievable its just getting the compentent porsche employee who can get it fixed. if not i will give up soon. use bluetooth for phone nav and just enjoy the ride!:)

If I understand you correctly the directions on your phone does not match the cars built in navigation even though your navigation unit has a cellular connection?
If that’s the case, they will seldom, if ever match.
Apple and Google spend millions of dollars and significant resources creating and updating their map services. Car manufacture just do not have the money or resources to compete. Essentially the maps data on your phone will always be more accurate and more up to date than what’s available on the cars system.

How is that possible if both connwctitnt o Google maps with real-time internet update connection? Had dealership run another test scenarios in other Porsches and their phones and they get exact matches in all cases

I could be wrong, but it seems like there could be numerous variables that would cause google maps or Waze on a phone to calculate a different route than the car's GPS.

The Navigation settings on Google Maps on your phone could be different. Additionally, it was announced that Google Maps would begin using crowdsourced data to influence provided directions. While the Nav in the car might have the Google Maps "Maps," that doesn't confirm that it will use the same navigation data that is used, which can quickly change on your phone App versus the car. The car may use some traffic data for calculating directions, but who's to say it uses the same traffic data that your phone does.

Regarding dead zones, it sounds like your techy like I am, so maybe look into downloading the map areas to your phone which is fairly easy, before going on your trip.

I think the premise that just because they are both powered by Google they should match. Neither the car navigation app nor Google Maps will be making the request for directions at exactly the same time. Ten seconds may make a difference. How many data points do you think Google receives about the possible alternative routes between two locations in those ten seconds? A thousand? 10,000? Do you think the processing power and speed of the car's navigation software is exactly the same as the phone? Do you think the cellular data transfer rate for both are the same? Do you think the processing speed or accuracy of the GPS signal is exactly the same? Are both GPS systems accessing exactly the same 8-12 satellites at exactly the same time? There are too many variables to expect the exact same result all the time. My wife and I can get two different routes from Google maps sitting in the same car at the same time.
 
#14 ·
Understand your points but this is different. Route differences of hours and not giving your any of the numerous shorter routes. I get not 100% but this isnt even close. Dealeship tested scenarios in other porches and phones and get exact match.
 
#11 ·
Ok just to be clear, you do not have an Iphone. Your car has apple carplay but you cannot use it. The google maps between your phone and PCM don't match route times.

Well there is a local guy here in Melbourne who has made an Android PCM fix so that you can use Google play or whatever it's called on the Android platform.

When I ordered my Macan back in 2015 I was almost crucified by my SA for NOT ordering navigation. It was a very expensive option that I knew was last updated in the Stone Age. He told me it would hurt my resale value. :unsure: Now that I look back I see it was the best money saved in my life. Having a Jurassic navigation system will probably hurt my resale value. Just enjoy Apple CarPlay and forget whatever Porsche has sold in your car.

having a nav even if it's compeltley outdated is great as a backup. We used to take back country roads to avoid traffic when we went snowboarding. On several occasions the phone signal died and we were in the middle of nowhere but the nav worked and got us where we needed to be.

what's BS is if you pay for a service that says it will give you updated live updates with traffic powered by google and doesn't deliver. This is a feature you pay extra for and it sucks you should get all your money back. I had all the bells and whistles on my S and had porsche connect plus and had sat maps and it looked great. But worked terrible. Ended up just using waze through carplay. Waze is your friend. Ask for your money back get a good car phone mount and problem solved.
 
#19 ·
they have already agreed to refund me but hoping to solve. finally got a compent person who has escalated and believes they can fix it. they confirm it should be as accurate and current and wayz, google maps, apple maps, etc. and have tested and confirmed on other cars.

Want to talk about a waste of money on factory navigation? I have a 2014 Mercedes C300 that come with "navigation prep". So then I buy a Becker Map Pilot module that plugs into the glove box. It costs more to do an update every 2-3 years, than to just use the iPhone navigation. My Macan did not come with navigation, but has Apple Car Play. Way better that factory Navigation. Even Lexus is starting to only order navigation if it is packaged with their Mark Levinson sound system. By the way....other than one of my cheap friends, who is still using Magellan???

I tried using Google Maps to route from my house (Alabama) to a known address in Charlotte, NC (the home where I grew up). I mapped the same route in my car (2021 Macan GTS), which was easy since the starting point was the same. The route the car chose was very different from either of the alternatives shown by Google, and longer. Just for giggles, I then mapped the route in Apple Maps. Apple Maps showed this longer route as an alternative. Strange - no other car we've owned ever showed this alternative route. For even more giggles, I mapped the route in my wife's somewhat new-to-us 2019 Cayenne S. It chose the same longer route as the Macan. Nobody in their right mind is going to take the 7:39 route shown below (from Apple Maps). It's a horrible horrible path to take.

Have you looked at your settings? You can get crazy routes if you say to avoid highways, tolls, etc.... Sometimes even Waze can give you some weird routes if you force it to follow some of your choices for driving.
 
#31 ·
It's a Porsche - it expects you to want to be behind the wheel longer! ;)

I thought the maps were static, but may be totally wrong on that. My Macan was a 2016 model, so I wouldn't be of any help anyway.

I have all the paid data and left NYC yesterday, headed to Palm Beach. Apple Maps and the 2091 Macan were 60 miles and 90 minutes different. South is south . . . .so I didn’t spend anytime investigating. 2nd trip in 10 days . . . . 1,274 miles at 74mph average.

ive got to look and see what map version I’ve got.

Just found this thread on Rennlist - Google Earth discontinued for 2017-2018 cars? - Rennlist - Porsche Discussion Forums

The thread initially discusses 2017 - 2018 vehicles, but does go on to additional info. It appears that is an issue for more than just your Macan.
thanks. this is only valid issue for cars with the the older PCM systems. 2019 and newer macans, 2017 a newer Panamera, etc. that have the new PCM system are not impacted.

This issue is also only temp for those affected cars per my discusison with customer service so the older models should get fixed to. its a contract that ended and they are finalizing the renogation of the contract with google

Not my Porsche but my Subaru. Between my phone (Google maps, Apple Maps, Gaia) and the car (Tom-Tom map, Apple Maps via CarPlay and Google maps via CarPlay and Gaia via CarPlay) i pretty much get a different solution wherever I look. The tech is so good and sucks at the same time. And I’m definitely a tech guy.

I haven’t tried it in either Porsche yet but I expect the same.

I feel your pain.
They will never match exactly and don't expect to.. maps are just outdated and not get proper updates via the internet
 
#45 ·
This may not help but..have you considered, rather than comparing navigation routes car vs. Google on your Android phone...to go to your dealer & place your Macan side by side with another Macan (or a couple if you cannot find another MY2019) enter the same destination & see if both cars give the same results. If they give different results, write down all the version numbers. (You should already have written down all your map & other version numbers for navigation.)

So, if the cars' navigation routes are the same you will have proven that this is not an issue specific to your car but to Porsche Navigation/map software. No chance of Porsche doing anything.

If, on the other hand, the routes are different, depending on the version of the various software, Porsche can get you updated. BC then you have a legit warranty issue.

Your thinking same as me. Already did that. Well not in person but had dealership run those tests for me and they validated inother macans and there phone nav matched in multiple scenario's. My in car nav maps are reflecting 2018 Iall locations, only the state I live in updated proper via the internet through google to update to more current maps.

I have a pending dealership appt but due to covid a month out which is why I've been trying to resolve myself.
 
#47 ·
OK...

We're SO FAR off topic in this thread now.

The OP wanted some sort of explanation for why navigation was providing such different values/routes
when asked for directions from A to B.

I'm moving the rambling posts off to their own thread in the Complaints subforum.



Thank you.

I've had factory nav in about 10 vehicles. Not one measured up to my iphone with Google Maps, then Waze. My Macan came CPO with Nav. Interesting that even though its CPO, they don't bother updating the MAP files. Without live map and traffic updates factory nav of any type is worthless IMO. I considered upgrading to apple carplay, but using the phone nav via bluetooth is fine with me.
