2004 H2 Onstar

[kmleong]

Just received my Bluestar and want to try installing it myself to save a few bucks. I need to know:
1) Where the Onstar module is to plug my Bluestar into.

2) How to get to it

Any help would be appreciated

Thanks in advance,
KML

You need to take your center bezel off your dash and pull the On-star in the dash. Your harness plugs right into the back of it.

Pulling the center off the dash is a pain. open your center console and pull all the screws out to remove the lid and pull the bucket.

Shift the truck to first gear and use a torx bit to remove the set screw in the front side of the shifter. Then shift to N and pull straight up on your PRNDL and cup holders to remove that piece. Then remove all the necessary screws and bolts from the center console so that you can slide it backwards.

Then pull your dash tits down towards the center console. Is held in place by friction clips. The On Star unit is bolted in with small hex head bolts. 8mm I think.

Then your on your own. Let us know how it works out for you!

Thank you very much for your assistance. Your detailed instructions leave me no room for screwups, but I'm sure to find some. I will attempt to do this install this week and will let you know it tuns out. Thanks again, Dennis

Yeah just a few.... lol

First time was the day after I brought it home to install my XM. I think the second was to clean the interior after the inside had gotten totally muddy from hitting deep mudholes while having the sunroof open. I think the 3rd was to install my CB. 4 was installation of my cellphone/gps mount with power. 5 was my front e-locker switch lol.

Too many times..... And I am sure more to go lol.

Hi i ordered one for my 08 it should be here this week and i will let you know how well it works in my 08. H2s in 2003 to 2007 use a class 2 bluestar and 2008 use GMLAN-29bit bluestar so their is some differences.

[lasvegash2]

Hi no problem, i will try to take some pictures and do a write up for a 2008 h2. I also have a lockpick gmx322 so we will see if they will work together.

Got it done today. Other than dropping my 8mm socket and watching it roll underneath my shifter, not too much trouble. The Bluestar unit is quite large, there is no room for it behind the Onstar module. I ended up taking the glovebox out to put it under the airbag switch. Used zip ties to secure it to the horizontal brace. Can't try the bluestar yet, dead battery. Thanks again for your advice. dennis
