How do I add a bluetooth to my 2004 Suburban. The steering wheel selector says aux and it had 2 xm radios available too but no Aux input on the front nor bluetooth

I would recommend Amazon. Check the reviews to make sure you get what you are looking for.

Install a aux add on harness open the link an it will provide you with what you need

no year, stated., so no real help.
get it serviced.
or check all fuses and connections to it, then get it serviced
the magic xm is busted.

after battery change auxillary line input will not work. All I get is rsc aux when i try to use.

Remove the 3 knobs for air system.
Remove the 2 small philip screws at bottom.
Pull bezel straight out.
Remove 4 larger philip screws on either side of radio.
Pull radio straight out.
To find out if your radio has "AUX IN", hold CD button for about 2-3 secs. If AUX appears on display your model has "AUX" connector in back. 2003 and early 2004 do not have "aux in".

That interface most likely is not going to work, because it is not compatible with all the gm radios, don't work good with XM and rear video system,
the problem is the wiring and the software on the interface,

the PIE GM12-AUX v2 works with all the radios in gm vehicles,
radio needs to have a BAND button and CD/AUX

There are 2 possibilities here:
Most Odysseys I've seen, have a small compartment on the left side of the third row that opens up to show a set of inputs (Audio and Video) as well as 3 headphone jacks with volume control.

WHat I did for mine was I purchased an extra long RCA audio cable on one side and a Stereo mini-plug on the other. I connected it back there where mentioned. Then I routed the cable under the rear door plastic plate and under the driver's seat, where it reappears under the center table.

Whenever I want to connect my iPod Touch, I just grab the plug, connect my iPod then raise the volume of the iPod all the way to the max, put the radio in XM/AUX and play away.

2) The second way to do this is a bit more complex, and will be the needed way if you do not have the A/V connectors in the back:
You will need to pull out the radio and the auxiliary connections should be in the back of the radio, or connected to the main radio plug.

I would recommend taking the van to an audio shop to do this installation.

Hope this helps!

I believe so, there are some audio jacks that are converters from a power source, such as, a lighter jack.

I haven't done this to my ridgeline, but I did it to my 1992 accord.  You can have any auto radio shop add a wire from the aux input on the back of the factory radio that comes out in a hidden place, like one of the little storage places under the radio.  Just plug it into your ipod and push the XM/AUX button on your radio, and you're good to go.  Should cost under $100.

YES,
See here for a description and picture of an adapter.

Good luck!
