Has to be said so long as i fits well any modern double din head unit doesn't look out of place .
Think the one I put in my 27 year old 80 series looks like it could be original equipment . For about £70 i got a Chinese unit with a map card slot , an SD card slot , built in gps navigation , CD player and a backup camera .
Its been in a few years now and the only thing i don't like about it is navigation wants an address rather than just a postcode so i usually use a Garmin on the dash instead . Run both at the same time and the route is identical .
