What's the correct wiring harness for replacing the head unit in the 2010 Vibe w/o moon and tunes?I got the one Amazon suggested, but it ended up being a reverse harness, so now I have two female harnesses that won't hook up.
The on-star harness isn't always 100 bucks I've seen it on ebay for like 50. For the 09-10 i think its the GMOS-LAN 02 interface. I plan on using one when I replace my headunit because I am going to replace my onstar module with costar so I can use the built in onstar mic for Bluetooth.
Quote, originally posted by dayday »Metra 70-2105 is what I used.After scouring the internet, that's what I ended up ordering off of Amazon. It should be here in a few days. In the meantime, I get to have my aftermarket JVC head unit that doesn't work, but looks cool.Thanks for the quick replies guys.
Has anyone completed the Onstar bypass with the metra 70-2105 wiring harness? any negative side effects? Just waiting for a little confidence before I order my new hu.
So I just bought my new HU for my 2010 and crutchfield included a Metra E5000Single pole-double throw (SPDT) relay. What is this piece? Did you use one?
