If i was a "Woman" i would have put my last post down to a "Blonde" moment ! :frown: :o
It's obvious you would have checked out that option before posting
The problems are :
1: finding a "reader/writer" for the "C-Map" cartridges ..... not easy ( but possible )
2: breaking the protection on them ... easier !
3: The C-map carts have very little memory, (32mb i believe)... and "street maps" are rather large , hence you would have a very small area coverage per cartridge.
4: you would need a lot of old ( but still expensive) carts to load with your "street maps"
5: for the price of a couple of C-map's you could have a dedicated car version
Why bother ?
