Well I decided to embark on a little project today and chose to mount it in the area behind the rear lights.
I raided the shed and found some left over Ply so I started building something to hold the cd changer.
With Changer screwed in
Attached in the car with 3 self tapping screws into the section where the first aid kit bracket used to be.
Just need to get down the scrappies and a get a bit of carpet to cover the ply and neaten it all up.
