Car is a 2001 Saturn LW200 which is the large wagon. I chose this because the radio console was not the deluxe model. It had a catch all pocket with its brackets screwed into bottom of AM/FM/CD receiver.
I removed the escutcheon, removed the 2 screws holding the radio in place then removed and disconnected it for reshaping the pocket brackets for mounting the scanner to. Then drilled a hole through each bracket for threading screws into existing scanner threads. (used common flat head screws) This arrangement mounts the top of scanner flat against the radio receiver.
The antenna is a Radio Shack through glass which is mounted on right rear glass behind right rear seat. The cable is run down side molding of rear seat, below molding on rear door, under carpet of right front seat to center console between front seats. Then forward and up behind dash to scanner. Power is also at an always hot source in center console (including ground) and runs beside cable to scanner.
A good quality speaker is plugged in to speaker jack and runs to floor and blares out of center console side. A Radio Shack cable (42-2472) is plugged into the PC/IF jack with the female (normally closed) end feed through a plastic knock out in bottom of ashtray (directly below temp control system). Excess of this cable is weaved back and forth to allow storing in the removed ashtray fitting and cover is normally closed until needing to clone with a Pro-92 or program with laptop. If cloning is needed, you will need the cable which came with scanner to plug between a 92 and the female end in ashtray. This then puts 92 and 2067 in clone mode. If laptop is use, the programming cable plugged in puts 2067 in clone mode ready to work with laptop and free Win92 software.
BTW, this car has around 40,000 miles towed behind a motorhome (reason I chose Saturn). A break away safety system is installed (in event it breaks loose while driving down the hiway). The cable (2 wire) controlling this system runs from its front mounting plug, through the firewall and is threaded through the knock out in ashtray and weaved for storing until needed for towing.
