ive decided to finally upgrade my single din eclipse head unit to one of these double din units. they are roughly the same price but the avn5435 includes nav function which i like but probably would rarely use. avh-p6800dvd doesnt have nav but does have the 6 disc changer built in which is very handy. neither feature really blows me away so i guess what im looking for is sound quality, screen quality, and user interface. if anyone can chime in on their personal experience with either one of these units, it would be much appreciated. gonna order by tommorrow.

 

I just got a AVH-P6800 the other day

I am totaly amazed by it. the controls are very easy to use the screen is nice and bright and the sound WOW!!!

I can't speak on the other model as I have never seen it in action.

Good luck with your choice! keep us posted.

 

Defiantly the AVH-P6800, here is my install

In my limited experience thus far with my AVH 6800 I have to say I love it....
