I am new to all this but have a similar question. I have an Iok chinese import and want to run a different menu to the firmware from the SD card so I can use a different media player, add addresss book, etc, etc. Someone suggested MioPocket but I have been unable to find a reliable download. Question is MioPocket still available or should I be looking for something else? Any help, suggestions or advice would be really welcome, but has to be in plain English as I have never played with GPS before!!! Many thanks.
