Love the 6620 but wish it had some extra features like:
- be able to control contrast, and illumination
- be able to load your own background pictures
- have FM info on radio stations (song titles, etc.)
- have Nav 3D modes on maps

They could have put a tons of extra options on that huge screen.

Now I need to upgrade the speakers. Any ideas on what has worked best for you?

 

Could someone please let me know if a pair of Kicker SS MB 8" will fit in the door panels' sub location.

 

Yes they will. I installed a set in my car with no problem.
