The maps have slightly more contrasting colors than before which is nice. I didn’t go through the themes, I think it had at least 6 or so originally. The texting interface with the phone is a little different, maybe just graphically.
Other than that and moving a few icons, I haven’t uncovered anything more.
Oh, and I’m not getting anything over AM. Not even crackles and pops when I manual tune to known stations. It’s like the tuner is not powered on at all. I might only use it once in a blue moon but I would still like to have it. I don’t know when it quit but I am suspicious.
