i wanted to change my standard head unit for an after market motorised tv/dvd combo my only queery is: does the standard head unit control any of the other functions on the car? i know some cars use the radio for power supply or other to auxilary components on the dash and i dont want to take mine out if its going to bugger it up and make some things not work.

if its just simply a radio and it wont bugger anything up then thats great il change it tonight

thanks

Nope, you should be fine in replacing the stock unit. You'll need an aerial booster and there's not much space behind the headunit.

dont forget the following

Ross-Tech: VAG-COM: Afterrmarket Radio Problem

Remember to swap over the Permanent B+ and switch B+ wires or you will lose your settings every time you turn off the car.

ok cool thanks, yeah i expected the wires to need swapping over was the same for my old vectra.

why would i need an ariel booster??

I think there is a booster on the stock unit which enables a good radio signal, an aftermarket booster retains that. If you are not a big radio listner then you can live without it. They are only £7 from ebay.

any idea what colour the cables would be?

Blue I think

both are blue?

The aerial booster cable is usually blue or blue/white. The switched live and permenant live will be different colours. Generally the permanent live will be a thicker cable than the switching live I think. Most aftermarker headunits will have the permanent as red and the switching as yellow but a lot of the time the cables have bullet connectors so that you can just swap the loom on the h/u round rather than having to move pins in the ISO connector.
