I am new to this so have no idea if I am doing this right. I recently purchased a 2013 ATS. I am absolutely in love with this car. On the other hand I am extremely frustrated with the navigation system. I have owned it for 5 months and have had it in the shop at the dealership 7 times to have the navigation fixed. They can"t find anything wrong with it. Basically it does not pick up my location and the GPS symbol has a line through it even on clear days. I continually shows me to be in a totally different place than where I am. They replaced the HMI cable and antenna......Does anyone know what else it could be? I am about to have to take it back to the shop!! I have not even been able to enjoy my car because it has been in the shop more than in my possession.
