I realize that instructions will follow with ordered unit, but I was trying to determine in advance if anybody attached unit to pre-wired location in the back. It would be a much cleaner install and I could use my shark fin antenna. However, per my discussion with BS it appears I will need to place unit in the front and use their antenna. It seems a shame that the kit would not use the factory connections. If you want XM this is the way to go. A side note - XM & Sirius are considering a merger per the Drudge Report today.
