    ? Oregon 750t problem

    Hi!

    I unlocked the latest TOPO 5 Sweden PRO and it works just fine in my Oregon 600, but my friends Oregon 750t refuses to read it (it reads other TOPO maps on the same SD card)

    Max map limit in 750t? Or do I need to use a different method to unlock instead of gimgunlock?

    Weird that other TOPOs works though...

    Any ideas are much appreciated /JensB
