[CL9] Sat Nav Whereis Version 18 available this year

[caudex]

Maybe you can burn a copy and someone close by can test to see if it works?

It doesn't work, MY12 is alpine reader, it will be using BAS files, where as the CL9 ones uses KWI files instead which is the Mitsubishi reader.
It is really easy to work out if your disk will work or not.

Simply stick the disk in your comp, look at what file type is the largest file, if it is BAS then CU2 Alpine (post 2008), if it is KWI then CL9 Mitsubishi (pre 2008)
