A www.disco3.co.uk resource Page 2 Introduction This has been discussed on a number of threads and I’m not trying to re‐invent the wheel here, just thought I’d put everything in one place for future reference. I acknowledge the majority of the procedures are not my own invention and credit is due to the forum members who have posted contributions in a number of threads. The pictures are all from my installation (unless otherwise acknowledged) on a UK spec MY 08 HSE, but item...

Parts required: SMB female plug, RCA female plug, length to your requirements of RG174 (or RG316) coaxial...

A www.disco3.co.uk resource Page 4 As long as you are careful, you can solder the screen to the knurled barrel and then slide the ferrule over the top and solder again. Dont get it too hot as you will ruin the dielectric.” As I did not have the special hexagonal crimping tool I soldered the cross braided screen and used a pair of thick pliers to gently “crimp” the outer jacket. This plug is a perfect fit for any of the three unused video inputs on the back of the factory SatNav...

A www.disco3.co.uk resource Page 5 To access the rear of the SatNav screen, you first need to take the H‐panel off, by pulling firmly at its lower end (lower red arrows). Then pull the upper end towards the cabin as well and it should pop off. If your fingers don’t fit or can’t grab the back of the panel, you can (at your own risk!!!) use an aid (in the form of a plastic wedge or flat screwdriver with the business end wrapped in electrical tape). (H‐panel in place...) (...and...

Then tilt the top of the screen backwards a little and wiggle it out of place by pulling...

A www.disco3.co.uk resource Page 7 You will now be presented with the built in diagnostics screen menu, one of which is “Video Inputs Test”. Press that. Now each of the three inputs on the back of your screen is available to “test” (or view in our case) by pressing the corresponding icon. Note that depending on your input source, you may need to press the PAL and/or WIDE1/WIDE2 option at the bottom left of the screen to view the picture properly. In my car, the system defaults to...

A www.disco3.co.uk resource Page 8 Part II – audio feed: Tools required: patience, time (total of about an hour including coffee/tea breaks – more if you decide to have a beer as well :lol: ), T20 Torx screw driver, soldering gun, thick pliers, needle‐nose pliers, hacksaw, metal file (or a Dremel tool instead of the latter two), cable stripper and heatshrink (optional). Parts required: RCA male to minijack cable, length to your requirements, depending on where your audio source...

A www.disco3.co.uk resource Page 9 The plug in question has two sections to it, we need the one with the red, blue and black wires. These are : RED: right channel, BLUE: left channel, BLACK: ground. Get your RCA‐minijack cable, chop of the minijack (keep this it will be needed later!) and strip the insulation. You’ll end up with something like this (red cable is right channel, white is left and each is screened in its own grounding mesh): Strip both the white and red cables and twist...
