The OEM units on Ebay look almost identical for the H2 and the H3. So will either one work and if not, what is the difference? The harness connections look the same too. And before everyone tells me to not do the OEM and find a good aftermarket...I am looking at the OEM options and then making my decision.

 

don't do oem..find a good afterarket.



but the best thing you can do is call the good people at pac audio and ask them....they make the adapters for oem head units and would know if they are similiar or can be adapted to fit.
