This is a follow-up to my previous post on factory/OEM vs aftermarket. It's a slightly different question so I've made it a separate post:


There are several of OEM cd/mp3 units for sale on Ebay from 2006 (head unit models AGC 5380TA & AGC-2380TA) and some from 2005 (head unit model AGC-6181TA).

The question: The 2005 & 2006 models look identical. Are they actually identical (even though they have different model numbers). And more importantly, will they work in a 2008 Aveo?

It looks like there is actually a newer and slightly different looking unit in the 2008 & up Aveos but I haven't been able to ascertain the model number of that one yet.

I know a dealer can probably help with this but my experience with dealers is varied. Some of them are more then willing to help with questions like these, others can hardly be bothered if they aren't going to make anything on the transaction.
