I've removed the headunit part ages ago and swapped it for an Alpine headunit but I lost complete use of my steering wheel controls and the Trip computer doesn't work without them..
Is there anyway I can get the MPG etc to come up on the screen and have use of the computer menus etc without the Sat nav being fitted??
Is it just a case of some changes in the wiring or does the Sat Nav headunit in some way control everything??
