Want to Listen to an Mp3 player or IPOD with your stock 2002-2009 Colorado Radio?
This is the Cheapest/Simplest Way to Do it
WHAT YOU NEED:
PIE GM12-auxv2 (approx 55-60 bucks) – Auxiliary Input
RCA to 3.5 mm conversion cable (3 bucks online)—cheaper wire is better b/c a slender wire will allow itself to be secured between the faceplate & the dash w/out having to drill or pinch
7mm Nut Driver
1 x Wire splice connector
The EASY PART:
1)Disconnect Negative Terminal on Truck’s Battery to cut power to all electronics.
2)Pull firmly on the lower portion of the faceplate that borders the center A/C vents, Factory Head Unit, & A/C Controls. Work your way up from the bottom to the top until this piece has completely separated from dash…
3)Remove the faceplate, making sure that the two electrical plugs (caution light switch & airbag notification light) are removed. Be careful not to scratch the dash with the rear part of the faceplate as it has sharp corners and can mess up your dash. I placed a sheet over the dash to ensure this didn’t happen. The airbag notification plug is a little tricky to disconnect so if you can’t get it, no worries, just set the faceplate upside down on the dash above the passenger airbag with the plug still attached & move on.
4)Remove the three screws that hold the head unit in place with the 7mm Nut driver and disconnect all plugs from the rear.
THE FUN PART:
This is the easiest way I found to handle the power situation.
1)Remove the PIE gm12-auxv2 from its package and assemble it by plugging the white 4 pin peripheral plug into the corresponding plug on the box. (be sure to pop the top off of the box and make sure the little jumper is in the XM position)
2)First stretch out the yellow and black power wires that are twist tied to the gm12-auxv2 and snip the connector off the YELLOW WIRE ONLY as you won’t need it.
3)Using a wire splice connector and pliers, splice the yellow wire on the gm12-auxv2 to one of the positive constant power wires on either of the two cigarette lighters located under the A/ C controls. Note the convenient hole in the dash to the left of the cigarette lighters; this makes for pretty easy access to the wiring.
4)Install the 12-pin connector from the gm12-auxv2 into the 12-pin female socket on the back of the head unit. Also plug the main radio plug & antenna cable back into the head unit. If you have a factory CD changer, you will need to install the 12-pin connecter that was previously in the head unit into the 12-pin female extension on the gm12-auxv2.
5)Plug you’re RCA to 3.5 mm conversion wire into the gm12-auxv2 box
6)Place the gm12-auxv2 box on top of the head unit and drop the RCA to 3.5mm conversion wire behind the dash & out the hole to the left of the cigarette lighter
7)Now it is simply a matter of setting everything in place. Secure the head unit in place. The final wiring step is to put the right head unit screw through the connector on the black ground wire and screw it in place. This provides a sufficient ground for the gm12-auxv2 and requires no splicing or soldering.
Secure the head unit with the remaining two screws and re-secure the faceplate to the dash (make sure to reconnect the two plugs that we disconnected upon removal).
9)Reconnect the negative battery terminal & turn on your radio.
10)The Colorado auxiliary input(s) work on the band button… Aux 1 & 2 should be located after AM in the cycle. If you have a factory CD changer, it should be located on the 2nd Aux input.
