H3 onstar delete

[jimmy p]

As I was splicing wires for my engine swap I noticed a single wire and inline fuse coming off the battery. It looks like this is for onstar. Does anyone know why this gets its own inline fuse rather than using a fuse in the fuse block?

Also has anyone removed the onstar module and associated components all together? I am looking to clean up and simplify my wiring, just wondering if anyone has succesfully bypassed it?

I do remember someone posting about this years ago, they unplugged something behind the radio if I recall correctly.

I unplugged mine only annoying thing is that there is a small red LED light on the mirror showing error with onstar

Really? I pulled the whole box and XM with no red light popping up on my mirror?

ain't tried it myself yet, but maybe it has something to do with the OnStar module being there & not working like it thinks it should (generating the fault light in the mirror) versus the module not being there at all (thereby not sending a status).

just spitballing, though

Ok thanks, that gives me some confidence to remove xm and onstar. My rearview mirror is already unplugged and covered by my backup camera mirror so no worries there.

Yeah, I did that same with cleaning up the wires back there and such about a year ago. You should be fine, I only did it because I got sick and tired of the GMOS going bad on me. Only down side that's not an issue to me was losing the RAP and door chime.

It may have its own fuse set up that way so you don't get any of the electrical hum or interference. My Ram has an inline fuse independent of the fuse box for the radio and thats what I was told.

ps: the Hummer's OnStar won't work now anyway since they deactivated all the 2G, 3G, and non-LTE cell towers last year.

Is that box behind the stereo only for OnStar and XM? I've installed a new deck, and if that is just dead weight, I'd love to remove it.

Well for what's its worth the H2 doesn't care if its powered down and removed. I did this on my 06 when I was trying to trace down a parasitic draw issue which by the way was the issue. Its fuse on my 08 has been out for well over a year, no problems.

I ditched it years ago and mounted my Icom base unit in its place. No issues outside of satellite radio.

Did you also remove the module behind the glove box?

 

[Korby7]

I kept that to tap into to run Bluetooth connection to the factory radio. Factory radio is finally starting to act up so I'll probably get rid of the module behind the glove box once I install a new deck.
