Hi Krunch,

Yes, I got this all squared away. What I did with my truck is that I researched accessing the radio and was able to get direction to open up the trim around the center display panel... after some nervousness because, after all, this was a brand new truck!  I found that when I removed the display panel, I could easily access the wire to the "shark fin".  I bought a simple antenna wire extension to fit both the back of my Onyx radio and to connect to the shark fin behind the display panel.  Not sure where I bought it, but it was an "internet search" find... maybe something to do with "XM radio antenna extension"... probably 20 inches long... male/female wire.  It is a very simple job to snake the wire from behind the display panel to the accessory plug area below.

Next, I wanted to make my accessory plug (bottom center dash) to power on only with key. (Mine was live all the time... not what I wanted) I tapped the fuse box by driver's door, ran a power wire under the dash over to the accessory outlet area.  I then bought one of those XM radio "plug in" power mounts to plug into the accessory outlet.  Once I mounted my Onyx radio to the plug in mount and plugged in the antenna pigtail (from the shark fin) to the back of the Onyx radio... turn on the ignition and IT WORKS!

It has been over a year now with absolutely no issue.  I was initially concerned that the plug-in mount might be flimsy (because the accessory outlet really is not built to support any real weight)... but no issues so far!

I have one subscription to Sirius XM for my Onyx portable radio... that I move from my Silverado... to my Volvo (daily driver)... to my Corvette... back and forth... simple.

I hope this helps.

DJ

I got the dash apart, I see 2 Sirius looking antenna plugs, one is brown and one is purple. Is it the purple one?

 

Thanx,

Krunch

Not sure if you are still waiting for me... but when I did it, I pulled the plug and turned on the old xm... if no signal connection, it says it and you know you have the right one! Your pic looks different from mine. Mine was exactly like the one pic I put in the post.

Yeah, I have no stock XM radio, only OnStar. I pulled both out and OnStar still appeared to be working. I will keep looking and maybe post something new that maybe a GM tech or someone with access to GMSI can help.

 

After much searching, I did finally find an antenna cable that would ship to Canada. $25 shipped, couldn't find anything local at all :(

 

Thanx,

Krunch

I'm curious as to how you guys brought the antenna wire out the front of the dash. is there an opening somewhere I can't find?

i don't want to put a hole in any trim panel or anything. or did you just come from under the dash and up ?

 

I have the stand alone Sirius unit with life time script. I ordered the antenna extension to bring it out of the dash.

I'm going to power it from the R.A.P. in the drivers side fuse block. As for audio input to the radio I'm using a Bluetooth transmitter plugged into the Sirius unit.

which will also be powered off R.A.P.

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.

      Is it time to put a piece of tape over the CEL?

      2015 Silverado 3500 right rear turn indicator failure

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
