HELP! 2009 Pontiac Vibe Aftermarket Head Unit Install

[bosk]

I just bought a 2009 Vibe w/ Onstar and stock radio w/o nav and was looking to put my Alpine IDA-x305 in. I looked on Scosches website and they say to use TA02B but the pins are completely different. I called Scosche and they said I have a factory amp and it was under my seat--none to be found. I told them that I thought it was odd that my OEM HU has a DC fan in it if it had a separate amp, but they assured met that all GM HU have fans cause they "run hot".Called Metra and they say I can use a 70-2105 or a GMOS-LAN-012 (The GMOS will retain onstar). Scosche has GM21SR that looks comparable to Metras GMOS (they have similar compatibility with makes and models). Suggestions?

I used the 2010 Aveo harness. Had to relocate one of the pins on the harness, as the 12+ constant (I think) is in a different location than on the Vibe. Other than that it works perfectlyOf course that's the part you use if you don't want to retain onstar... EDIT: Scoche P/N GM18Bhttp://cgi.ebay.com/ebaymotors...t_939

Pretty sure I used 70-2105 ( listed as '07+ Monte Carlo I think) it had everything except for one power wire that I chose to wire directly to the car's harness. It does not retain onstar.Unless you have the stock sub in the cargo area you have no factory amp.

Thanks!! It looks like the scosche part is cheaper than the metra part so I am going to do that!Was it the 12 Volt/Constant (yellow wire) or the 12V/Switched (red wire) that you moved? The reason I am asking is the wire that dayday is talking about I think is red because metra says youll have to wire that into the car yourself and gives you red wire to do it and references the 2010 Chevy Aveo, see install note here: http://www.metraonline.com/fil...b.pdf

hmm, maybe it was the red wire, I don't recall. I'd have to look at my harness to figure it out. Will check tomorrow for ya

sorry for the wait! I've been working late & haven't had time to check. Pulled apart the dash after work today. it was the red wire I moved.... still in the bottom row, but moved to the spot to the right of the green wire. I've included a pic of it.

Hello Bosk and VibeBear! Thanks for keeping this discussion going on here regarding installing the GM18B with an 09 Vibe. I followed what you both did down to moving the red pin wire where it needs to be. My head unit turns on. But I get no sound out of my speakers. I played with all the settings on my head unit, still nothing. I have the head unit connected where the stock radio was in the Vibe and have left the Stock amp connections plugged in. I do not have the radio antenna plugged in to the deck as I do not need it, but, if these needs to be plugged in for this to work, then I will purchase the antenna adapter.

I listed some specs below about what I have if it helps. Please let me know anything that might be of help. Thanks in advance!

Car: 2009 Pontiac Vibe w/ stock amp and sub and OnStar
Head Unit: KDC-HD548U
Harness: Scosche GM18B

the reason you aren't getting sound is probably because the amp turn on wire isn't connected. Make sure the blue with white stripe is connected to the blue wire on the harness. Not sure if the blue wire is in the right spot on the harness though.

You must use the blue/white wire on the deck as the solid blue one is for a power antenna and will not provide power when listening to a CD iPod or aux input

Thank you for this post. I have a 2010 Pontiac Vibe with standard Audio system plus onstar. Used the Scosche GM18B. Moved the red wire to the bottom row to the right of the green wire. It was very easy, if you do it right. Use a small, flat screwdriver to pop open the black plastic latch that give access to the pins. Press very lightly on the little silver clip that holds the pin and pull the wire. Don't press to hard like I did, you'll have to dig the latch back out with a very small tool. Just pop it into the now position and you're good to go. I dd not use the blue remote wire, solid orange wire, or black wire. I directly attached the black wire from the radio to the chassis ground bolt in the lower right of the dash opening. Also needed an adapter forte non-standard antenna pin.

Don't use on-star, so I can't comment on that, though I'm sure it doesn't work. Everything else, including antenna and dimming, works. Let me know if you have questions and I'll try to answer them.
