Right guys, bit of an update !!
I coded my new unit with the coding from my original japanese unit...and guess what....i lost all my UK FM channel frequency again !
so went through the bytes one by one changing them until it changed back and found out that byte 9 on the jap unit was 33, byte 9 on the uk unit was 11, changed it back and hey presto, FM channels are back !! so it looks like it was just a coding change for the frequencys !!
i still have no nav working though now ! or no compass in my clocks, just says no nav data
so im thinking, what will happen if i put my old unit back in and change byte 9 to 33 ? i should be able to get FM channels but doubt the nav will work !!
i have got the coding numbers for both units so will put them up on here to see the differences if anyone can advise me on what the bytes mean ??
