I noticed an earlier post, and wanted to offer some tips, after just successfully mounting some gear in my Patrol. I also don't like "destroying the "trim", and any parts I drill I buy spares for, so that I can go back to "standard" trim for resale (in say 5 years time).
1. Mounted a Uniden UH090 CB/UHF (ultracompact) into the long black vertical panel running from the console lid, adjacent to the drink holders. This was easily achieved by using a Dremel tool to cut the plastic (you can buy a new plastic piece for abot $11 if you want to go back to standard trim. The internal speaker is easily heard, and the mic lies in the gearstick boot.
2. Mounted a Nokia 6210 handsfree kit just in front of the console cupholders, on the passenger side - single drill hole mount, and sat the external speaker under the console, accessed by removing the ashtray (it goes into that hole, and site under/behind the ashtray - easily heard, and out of sight. Mounted the phone mic next to the overhead console (to avoid wind noise from open drivers window).
3. Removed standard 6 stacker and mounted Sansui DVD/MP3/SVCD player in bottom DIN slot, and Sony head in top DIN slot. High Power amp sits under the front of the passenger floor mat. DVD is connected to aux inputs on the Sont head. 10 Stacker mouted under passenger
seat, using cotter pind through the carpet.
4. Mounted Super 7" TFT video in roof, just to rear of sunroof. This provides DVD and aux feed from CCD monitor camera in horse float.
5. Mounted Electric brake control in plastic centre dash cover, the one thats just above the front of the console...easy access, and a new plate is just $8 to go back to standard trim.
6. Mounted Piranha battery controller under bonnet, with H/D cable to rear Odyssey battery in enclosed box at LHS rear of cab. Internal wires from that feed the fridge plug mounted at the rear of the console (next to the ashtray - single hole), and also runs the UHF and DVD/Stereo (all audio gear wired with power line noise filter).
7. Made a false floor in two parts (remove the rearmost seats, when carrying stuff), and rear false floor sits on the two side
seat mounts - allows a three burner BBQ, stand, cooking gear and aluminium folding table/chair set to be stowed underneath. I remove the centre seats when we go "car camping", and drop in the front false floor...the Waeco fridge sits just behind the passenger
seat, and plugs into the plug at the rear of the console. When the front floor is fitted, there is room under it for clothes, rescue gear, utensils and gas bottles. The full floor permits an extra large mattress, and great sleeping accomodation for 2 people - without having to shift any gear out of the road to sleep (and no crap up on the roof).
8. Fitted flyscreens to the inside of the two rear door windows (with self adhesive velcro, and re-wired the window controls so they can be operated anytime (without IGN or ACC turned on).
