XM install on 06 Vert
 

My wife got an XM Xpress unit for Christmas. I am trying to install it using the supplied sure connect FM Modulator. It hooks to the base of the antenna and then connects to the unit. I am trying to get the wire through the firewall and can not seem to find a good location. Does anyone have experience with this unit or running wires through the firewall? Thanks for the help!
