Hi Thefatboy,

I encountered the same problem faced by TerraToss but after spending hours searching for the solution, I finally found it at one of the forums where I downloaded Jet Mouse 1.5 + Checksum Fix. It solved the problem. Subsequently, I loaded the unlocked map to my Nuvi 260W and check out the map. What I discovered is only the map of Jerome Wee v3.85 appearing but the mfm 090914 map went AWOL! I find that weird as I thought that this mapset was generated using mapsource where the original sub-mapset of Johor and Singapore was replaced with that from JW's v3.85.

Do you have any idea what went wrong or where the fault is? :o

Please advice.

Thanks.
