Don't use my OnStar so not sure, but I think it only uses 1 channel/speaker, not stereo.

 

on the radio conn 2,pin j is left,pin h is right, pin k is shield. you know me, i never type b4 i check facts!
that audio would only be heard when onstar is active?. dont know how it gets done,or how it tells the radio to take it

 

drtom, I will try it out when I got really bored some day. Do you have a diagram of the radio conn 2?

 

u can download the entire manual for 10 to 15 bucks.

look for hummer service manual

 

Hello,

Is it possible to change the frequency of the radio by one step at the time?
I mean, now it jumps for example from 91.3 to 91.5 to 91.7 and so on.
Where are the 91.2, 91.4, 91.6??
Is it even possible??

Thank you

K.

 

it just follows the channel spacing,,so it goes with new tech "progress",no analog tuning no mo

 

Hey K.

I know you are in Belgium and they use the same FM channel center frequencies ending in 0.1, 0.3, 0.5, 0.7, and 0.9 megahertz (ODD MHz), some countries use "ODD MHz" channel center frequencies as well as channel center frequencies ending in 0.0, 0.2, 0.4, 0.6, and 0.8 MHz (EVEN MHz).

So unless you travel to those "other countries" you will have no need for the "even MHz" channel center frequencies.

 

Hello Tainter,

Thank you for the info, but some radiostations i like to listen to are just like 99,4Mhz :-(
I can listen to it but it is not clear.

Bye,
K.

 

The radio pin outs are different for the H3 vs. the vett. I've spoken to Ray and he can create the short piggyback cable that will allow you to plug it directly into the back of the radio. It has a short jack cable that can be run to one of the aux light dummy plates in the cover if you don't have that option. It is an H3 version of his AUX-3 option. Seems like less work then the XM plug since it is a much shorter run and you only have to remove the radio console cover plate to get to everything. It is not a radio controlled iPod option like a PAL unit, but it will allow any audio device like a MP3 or iPod to play in true digital and it works with the Monsoon option. Not as cheap as splicing into the harness yourself, but you don't loose XM and it can be removed if the need ever arises.
