Hey guys, I have a 2006 A4 and i was looking into buying the portable Sirius Satelitte Radio (Stilleto 100). The only thing im afraid of is the fm transmitter will be too weak and i will want to have a hardwire connection to the backof car radio which would obviously sound best. I was just wondering if anyone knew how to use the Sirius hardwire radio kit to wire it into the back of the car radio system (ifyou have to take the radio out and how you do it, or not etc...) . I could be wrong (and i dont know where i heard it) but i heard through the glove box on the left side of it on the top shelfthere is a hole that you could open that would lead to the back of the radio. Also, if the kit is simple enough for me to do or take in to have it proffestionally installed. If anyone knows any information, knows how to install it, tips or anything, it would be greatly appreciated, because i have no idea how to begin to go about installing this thing through a wire to the radio. Thanks!
