Z4M Roadster Electronic Interference

Hey all,

Completely random. Since I have owned my Z4M, I cannot get a GPS signal, on my cell phone, in the vehicle when traveling above 30mph.

Different cell phones, different service provider, different areas, etc. Lose GPS. Data and cell works fine, and it is super weird. Can have two people in the car, completely different cell phones and service, same problem. Both of us cannot get a GPS signal.

Top up or top down, doesn't matter. Just can't get a GPS signal above 30mph on my cell phone and at that - it is flakey.

I have a feeling there may be a botched install of an old LoJack or something along those lines in the vehicle from before I purchased it. Where would I even start with this? Ripping apart the entire car and looking for it? Finding someone that can potentially track RF interference or similar?

I assume I am completely alone in this..

Thanks everyone.

Very strange. Does the car have navigation? If so, I'm wondering if the car's GPS antenna can somehow (malfunctioning) interfere with the phone's GPS capabilities. Just a wild ass guess.

No navigation.

I spent the weekend combing through the car, laying under it, inside of the trunk, under the dashboard, in the hole where the radio is, etc.

Only place I didn't take apart was the behind the seats, so that is next I guess.
