Hey guys,

I've tried searching but haven't found much in the way of easy to find, concise information on this topic:

Who makes the best aftermarket DVD navigation non-portable system for installation in the trunk/under the seat, and controls through a touchscreen LCD mounted on the dash in the Mazda Nav Tray that CanZoomer sells?

Criteria:
No portable systems
No carputers
Just DVD navigation

Are they able to do voice-over-music? Who has the best and most legible maps? Who's got the alternate route finders? Points of interest? The newest system? Gyros and speed sensors supplementation to the GPS receiver?

Systems I've found:
Alpine NVE-N852A DVD-based PowerNav systems
Pioneer AVIC-88DVD
Kenwood KNA-DV3100

Any others I shouldn't miss? Any experiences with any of these systems?

Lastly, I tried looking for COMAND systems that Mercedez has in their systems, but no luck. Any info on MB/Lexus/Audi systems?

All help will be appreciated. All trolling will not. Thanks!
