4WD Head Unit

The aftermarket Android Head Unit was delivered today.  Shipping from China was very quick and I was pleased to see it had been well packaged.

Our original head unit is a 2DIN and consequentially quite deep.  I assume because it included a DVD player.  The new Android Head Unit doesn’t have the player and accordingly is roughly 25% the depth of the original.

The screen is larger (9inch vs 7inch) which required a replacement facia.

components

Included were

  • Head Unit
  • Facia panel
  • Patch lead to convert the exiting 4WD wiring to the new unit
  • GPS dongle
  • Two (2) USB leads
  • Reversing camera and cabling
  • Patch lead to convert the existing rear view camera wiring to the new unit
  • Patch leads for accessories
  • Patch lead for the original FM radio aerial
  • Plastic trim removal tool

Connecting all the cables was rather simple, although I found I had a loose red and black cable with no connection.  Eventually I realised it was the power cable for the fan inside the unit.  Then looking through all the patch leads I identified a grey & black cable with a fitting that appeared to fit

Does the Grey/Black cable connect to the Red/Black?

No screws we included to secure the unit to the facia but after several minutes of searching in my various “you might need these one day” jars I found some that were suitable.

The unit has a built-in microphone, but these are usually poor quality.  The accessory patch lead has a socket for an external microphone and I’ve therefore decided to buy one from Aliexpress.  I’m also going to buy a plastic screen protector in an effort to avoid scratches and minimise glare.

what I now need is a fine day to do the installation.
