At this point I really don't know. I did like what I saw when I looked at the Eclipse units. They seemed to do everything but control the Ipod thru the HU, however a new model above the 5435 is coming out, maybe it will integrate the Ipod???
So far I've not seen one that does all that I want it to do so either I wait and keep looking or go the opposite approach and get a HU that works with the Ipod and a handhelp GPS/nav device. I'd prefer the all in one unit but who knows when that might happen. The other option is to get a unit that will work with the Ipod but use the aux ports instead of controlling it from the HU.
I wonder how much that will bother me in the long run. I mean that's how I use it now with the Itrip and it's not great but I'm definately used to it so it wouldn't really be a change. However the sound quality would be MUCH better.
Do you know where you are heading???
