I have just purchased a 2012 Liberty Artic edition. It has a 430 rbz radio in it that has no navigation and the hands free features are "not available". My questions are these: Is there an update to add the non-working features or does it require a new radio purchase. And, I have NO compass, anywhere. I am directionally challanged and it nothing else I need a compass. The dealership wanted to sell me a $300 rearview mirror with a compass and thermometer but I was hoping there was another option. Any ideas or thoughts would be appreciated, as I am totally ignorant of the solutions. Thanks!
