kenwood dnx7100 all in one gm antenna

Ok, I was looking for a way to get the GPS antenna that came with my kenwood off the dash. Its one of those cheesy looking little square ones. I found an antenna that comes from the factory for GM vehicles that has three coax outputs on it, one for XM, one for Cellular, and one for GPS. My first and most important question is: Is there any way to make this work with my Kenwood Nav unit (DNX7100) THe Kenwood has a funky gray plug on it for the GPS antenna, its round, about 1/4 inch diameter. Also, I am in the process of building a carputer that I want to use with a wireless aircard from AT+t. is there anyway to link the aircard to this antenna as well? The antenna base part number is 25773456 and the mast part number is 25758073.

dude y dont u just hide the antenna under the dash plastic!  not all cars will work but on my 05 avalanche its under there with great reception. as long as theres no metal above it it will work great

ok, sounds good to me
