I'm having problems with my navigation everything on it is working fine except its not tracking me when I'm driving its just as if I'm creating my own road, there is no GPS showing up under the compass on the screen. Also I just put a bunch of the Dynamat extreme in the trunck including the rear deck mabey thats interfering with the signal

someone please help me out

 

Isn't the Nav GPS sensor/antenna in the rear deck?

 

ya I think your right isnt it in the bottom part of the rear window i''m gonna try taking the dynamat off that section and then see if it works thanks

 

I think you've identified the problem (blinding the antenna).
