My '99 2.8 Z3 was imported in to New Zealand from Japan and subsequently has FM frequencies incompatible with just about the rest of the world. Am trying to source a BMW original UK or USA head unit to keep the car as original as possible and still control the CD unit in the trunk (or boot) depending where you're from. FM frequencies need to be in .1 hertz steps up to about 105. Any clues anyone ? - Cheers, Bob
