It's got an IMEI number so is it a cellular connected tracker?
Unfortunately, I don't think so. No radar detector needs a power module like that. Page 6 here tells you what comes with the Uniden R7 and there's nothing that looks like that. https://www.uniden.info/download/ompdf/R7om.pdfthanks. I figured it out. It's a loose power module from the Uniden R7.
