I purchased my 2011 in Mar of this year and only recently had a chance to look and finally drive it. Every thing works in the car except for the nav. Took it back to the dealer to get it diagnosed only to tell me some thing i already knew. They said that it would have to be replaced. I asked them being it was a new car if i was going to get a new nav system, and they said i should be able to get new one. Parts made the phone call to order the nav/radio system only to tell me that i would be getting a refurbised system. To say the least i told them what i thought about putting a used nav system in a new car with only 25kms on it. I didnt let them order it yet as i am not done with this yet. I am going to call customer serv on monday, but i am sure i know where thats going. Any ideas on getting a new nav as this is my 5th challenger i have bought. later.
