    Hey agent005...I have 7 years installation experience with mobile electronics, although i've moved on to law enforcement, i still know a great deal about these things. I have a 2000 Silverado myself and just installed my DVD/Navigation/XM Radio/I-Pod adapter yesterday. To my knowledge with the factory installed XM Tuners, they are not compatible with ANYTHING for the sole purpose of the dealer making a profit and their current contract with XM. I can definitely assure you the Portable units are not compatible with the direct connect fully installed units. Now if you get on the phone with XM, you SHOULD be able to link the two radios to the same account for a reduced price, they offer alot of deals and combos for multiple units. I know this isn't the news you wanted, sorry pal, just trying to be helpful.

    I'm going to be a mission now and call around to some of my old install buddies, see if maybe they've been updated on a solution to this for you, give me 2 or 3 days to make some phone calls and i'll repost here for you. I'm all about find free answers if i have them, knowledge should be free :)

    Going to keep my eyes on this thread...I want to do this just havent gotten off my butt to do it...

    The factory XM tuner is behind the glove box if nothing changed between 07 and 08.
    I was told on another forum all you have to do is trim some excess plastic off the atennna connector to get it to work with a aftermarket HU.

    You may be hard pressed to get it to work with a portable unit. I have 2 radios and I tthink its 14 bucks each a month....to be honest i havent looked at the break down of the bill...its like 60 bucks every 3 months.

    you can do it!! we do it all the time here at my shop. (on the new ones anyways) the XM module is behind the glove box. just drop the glove box down, you dont even have to remove it. the antenna plug is brown and itll be lookin right at ya! the only thing is, we utalize them on the hide-away xm units for an aftermarked deck. we usually hide them back behind the glove box as well.
    the problem your going to run into using a portable, is the length. we have splice and extended them before with no reception problem, but for my own sake and protection, im gonna tell you to not do that.

    you also might have to remove the actual antenna from the brown housing. just be careful. hope this helps! good luck!

    Ok, so I am going to do this in the next week....the wire is definately to short to reach the pioneer XM brain - which is to the right of the head unit kinda stuffed in between the vent and glove box.

    Can I cut the XM wire to the magnetic antenna and splice it to the one you have pictured...and what kinda wire is it..... can i use a wire tap?

    If I screw it up the worst thing is I have to run a new antenna...so I wont be mad at you!
