Other than the RB1, which I do have already, what is the best fitting Nav radio that has the "most" features? I would like to avoid modifying the dash if at all possible. That is why I went with the RB1 a few years ago. I just picked up a 2014 Wrangler though with the upgraded MyGig radio and Nav system and that is probably one of the best radios I have had in ANY of my cars over the years. It has so many features it's hard to believe it's in a jeep! I loaded 680 songs into this thing and I swear the sound quality is better than when played off of any CD. The automatic link to my phone and using the radio to adjust the phone call speaker volume is super nice. Now I want something with the automatic Bluetooth phone system and hard drive for all the songs. Anyone set something up similar to this in their car?
