Im looking to upgrade the headunit and speakers n my 2002 astra sxi. But i have a few questions i was hoping you guys just may know the answers too.
Firstly the standard headunit uses the head up display on the dash to give radio info, is it possible to get a aftermarket one that will still display on this (aswell as on he headunit itself) are there cables to do this? Also what about the steering wheel controls? i dont want to really lose the use of them. I wouldnt mind losing the dash display, but would it still work with an aftermarket one, i.e display temperature, date, time.
I have also heard rumours that space behind the dash is tight and certain aftermarket headunits dont fit, any truth in this?
Secondly does any1 know the sixe of the standard speakers, as i want to get replacement ones the same size, just better quality.
