GM XM Kit

[H2Chuck]

Ok I need some help/advice I have the 12498768 I think is the correct # kit to install the XM .
Q-I dont want to drill holes in my roof with the sunroof etc.The antenna supplied with this kit comes with a roof mounted antenna that you HAVE to drill and mount so,that being said ,has anyone researched the aftermarkets and came up with a solution.I have just about exhausted all areas.
one install shop did try to sell me a micro-mini single lead Terk model but,the connector into reciever will not plug in.They did say i could go from the single wire into a dual wire out and just use 1 lead of that splitter?I need some help.could i take the plastic connector from the lead off and plug it in that way without any lose of signal?I appreciate any help.
