quick question i currently have the z2 installed in my 06 Nissan Frontier and just received the GEX-P10XMT. do i still have the to connect the antenna to the box even though the Z2's is already connected? will it work off the Z2's GPS or does it need its own "signal"?

Tahnx in advance

You will need both antennas

i was hopin u wouldn't say that

Actually, I just installed a different brand receiver in my son's Frontier. I put the XM antenna under the cowl completely out of site and ran the lead inside. Piece of cake.
