It seems that the USA SPEC's compatibility with the 05 and 06 has been pretty well validated.

What are these things going for out there? I can get them and offer them to forum members, but I need to know how cheap I have to be able to get them for it to be of interest to you guys. Let me know, thanks!

 

They go for $140 at Crutchfield, typically. Worth every penny.

 

If I can get them for $120 and $135 with the nav harness, would that be good for you guys?

 

Ken, FYI: I got mine for about $110 + shipping at enfig in early July, but it looks like their price has gone up to $135 (wo nav harness). So $120 would be attractive today.

Installed in my 04/Non-nav; works fine even though the 04's weren't listed on the USA-Spec compatibility list at the time. I think they are now.
