i have a 07 vectra estate with the (older model) cdc opera which is not mp3 compatible im wondering, if i upgrade to the cdc mp3, (from 08 models onwards) is it a straight swap, will it work with the standard display screen?
As said it can be done but you'll need to divorce the old headunit and screen so you can pair it to the new stereo. It would have to go to Vauxhall or a good garage that knows their way around Tech 2 to be sorted.
