I've just purchased as 02 Astra SXi which is fitted with a CAR 400. I'd like to fit a new HU which has support for playing MP3s, preferably with USB and or SD input. Obviously I'd like the steering wheel controls to continue to work, and ideally I'd like to keep the separate display working.
I'm on a fairly tight budget and frankly a little confused with regard to the options. Can anyone recommend an appropriate HU & set of leads, or ideally suggest a site from where I can purchase a kit with the required interfaces?
I'd be grateful for any help you can provide...
