When I launch the map app from the head unit, I get an error saying a GPS signal can't be found. The map then shows the entire USA, and I can't locate the car.

But, when I check the radio settings, the GPS Check says it is getting a signal.

Any suggestions?

Thanks

Do you have location services activated in your phone's settings?

Like you, i made the mistake of assuming the GPS device could totally replace the need for the iphone GPS/location services. Unfortunately this does not seem to be the case, and is more of a supplementary device.. i use something called the bad elf gps which attaches to any of the current iphones/itouch/ipads that does infact replace the need to use location services, is more accurate, and means 3g is not needed.

Did anyone find a solution to this problem. I'm having the same issue. Location services is on for maps and the gps in the radiois getting a signal
