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.

 

call the good folks at pac audio..they make adapters for stock radios and would know for sure. Personally I don't think it will work but ya never know
