hi, have just followed J Seaman's really good advice and photos on changing clock in x300, got my motorcycle/car clock from a well known auction site for the grand sum £5.45 post free..the only difference was that I left the time change button on because my soldering skills are not that refined so I have the time change button just at top of ski slope( cannot be seen from seats) but quite a neat place.. thanks J Seaman!!!! regards J Wright...
