Head unit options.

[calisonic]

Hi there. looking to up the sound system in my 2011 rex, it has the navigation unit, which has no balls however I don't want to trash the thing and I do want some sort of navigation up there, and I will be adding a sub.
I was wondering if:
1. Is there a market for the factory navigation head units to the point where I could sell mine ?

2. Could someone advise on a good navi head unit that is responsive. My biggest irk about most of these is that they have so much lag in the interface, it drives me nuts. Also must have headphone jack style aux input.

If there's no market for them then I will just add the sub for now, the factory unit doesn't have terrible quality, just can't hear it on the interstate (90% of my driving).

Edit: Also, will a regular double din fit in there or will I need another bezel or mounting kit, thanks!

Thanks!

I installed a double din pioneer AVH2400 in my 2013. it will fit but it came with a monting kit trim piece for the outside edge of the head unit . It gives it a finished look. If you want I can send you some pics of it. It also has a navigation option with it but I dont know much about it. I didnt get the nav. with it.
