I'll post some pics for you when I'm done (still need to wire the power and antenna) but essentially I mounted the remote part of the Cobra 75 cb underneath the downward triangle shaped panel (beneath the arrow coming off the 5 in the diagram) and then routed the connector thru the dash and it comes out just about where that arrow points.
I had to drill a few holes in the back panel (not visible though when the front panel is on) to get it to work but it looks good.
The main issue I ran into is the wire from the remote box to the connector isn't very long.
They give you a trim piece and grommet for it but the there are limited ways to utilize it for in dash because there isn't enough wire to route to where it needs to go from where you would logically mount it.
The instruction manual says to mount it on the firewall and just run the cable out from that but I didn't want the connected cord dangling around my leg as I'm driving. So I disassembled the center console and found a place instead.
Honestly it was a PITA to get it to work there but depending on which center console you have in your 06 it might be easier for you. Good luck.
