I am replacing the ISO Blaupunkt 520 in my 02 TS Astra with a Kenwood KDC-MP5043U.
I have read all the posts about display issues etc, but I want to keep my existing connector (i.e., the Vauxhall/Holden one) and actually wire the new unit through it.
I was even thinking of unscrewing the connector off the back of the ISO and trying to match it up that way.
Has anyone ever done this?
Of course, I want to keep the date, time, temp etc.
Can anyone point me to a wiring diagram FROM the car or know the original colour scheme.
