Anyway, A more in depth version of my install as promised.
My old existing head unit, still selling for £200 - only been in 8 months lol
used a double to single din adapter to fit it.
loosen the centre panel facia and handbrake assembly so that front console can be pulled forward to gain access to stereo for removal.
removed old head unit.
New double din facia adapter. so that the new double din head unit fits nice and neat
The GPS And Freeview Antennas
installed the GPS antenna just in the cavity under the drinks holder in the dash as shown in the picture:
installed the freeview antenna on the windscreen by the rear view mirror.
New double din assembly for head unit
sorting out remote steering control wiring.
wiring config:
black/red cable = common
Black/White cable = switch 1 / key 1
Solid black cable = switch 2 / key 2
Also installed an iso plug for the steering controls, so it can just be unplugged if i ever need to remove the new stereo. makes life easier.
(also soldered another one to the head units connections)
Thats it, All done !!! finally !
Marks unit is next
thanks !
