Hi all, I am wanting to know what Vauxhall stereos will fit my 97 Mark3 Astra CDX with remote display? I currently have a CDR500 and would preferably upgrade to a model that will control a CD changer. I have been offered a CAR400 which appears to have a "0" button - does this switch mode between CD/cass/tuner once added? Will this drive my car's display? Any help/advice appreciated (or anyone who's selling a second hand item!) Thanks.
