Re: 2012 overland owners, check your radios
I just picked up my 2012 GC Overland last week and this was one of the first things that I checked. I ordered the car on 12/03/11 and picked it up on 01/21/12. It had the 40GB radio with 20GB of free space.
I also requested that the dealership update the radio/nav software to version 2.120 software but they did not, claiming that it had the latest version from the factory. So it seems that the factory does not have the latest version available yet. I ended up updating it on my own using a USB stick. Took about 35 minutes to complete. So far, so good. No issues yet but then it has only been a week.
