Hi, everyone. I own a base '12 Volt (129k miles) and I just got a premium '12 Volt (42k miles) with Bose system and navigation. The navigation is nice, but so far, I prefer the stereo on the base Volt in that I can play music on my Android phone via Bluetooth and use the dash and steering wheel controls for just about everything. I can't do anything with my phone on the Bose system other than connect it via aux input. USB connection didn't do anything. If anyone has any input on this, please let me know as the forums that touch on this subject are pretty outdated. Also, not sure how to add vehicles to appear at the bottom of my posts.
