Need new head unit - suggestions?
 

Truck: '07 Avalanche LTZ

The MENU (which is also on/off) button on my Kenwood DNX6990HD double-din head unit stopped working. I had to push the reset (red triangle light) to get it to turn on. Problem is, it sometimes turns off at random while I'm driving.

LOVE about this unit: Built-in Garmin GPS, volume dial (I really dislike up/down volume buttons - I like to just turn it to where I want quickly, without having to look down).

Can you guys/gals please suggest a new head unit that has both a volume turn DIAL (I have to use that word as it thinks k-nob is a profanity), and built-in GPS? (and of course, plug-ins for my backup camera, GPS antenna hookup, my external USB cord for playing music/movies off USB - or at least a front USB port)

???

THanks in advance!

Hmph :(
