Xm Hard Wiring Power

I have a 2007 NBS GMC Sierra Crew Cab and recently had an aftermarket XM radio installed (Audiovox Express). The installer at Best Buy says that the new 2007 Sierra's have a different type of power connection for the factory radio which doesn't allow him to tap into this for switched power. He was unable to find any other switched power source to utilize for the XM radio. He ultimately hard wired the XM radio into the fuse box but it is not switched.

 

This is a minor inconvenience. Just wondering if anyone has any ideas or recommmendation for switched power on this unit?

 

Thanks,

Is this integrated through the factory head unit, or is it a separate unit with its own display? GM makes an XM kit for $225 that I installed in in little over an hour on my NBS '07 GMC, and works right through the head unit. Everything was plug and play. Kit came with a new antenna to replace the Onstar antenna, so both systems can share the same antenna. No additional holes to drill.

 

As far a switched source, PAC makes a unit that is used when adding an amp. I don't know if that can be used or not. The BCM controls so much any more. Much of the wiring in the new trucks as constant low voltage at all times. You have to be careful what you tap into on the new trucks, because you can fry the BCM, or cause other system features to blow fuses. I'm not a fan of tapping in at the fuse box. That's really not a good solution.

An option is to get a aftermarket headunit with XM capabilities. My pioneer has a sirius module, but you can get XM modules for any satelite ready unit. If you know the positive and negative or ground, at least on the older ones, you can hard wire them.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
