I am just going to try to update an old GO 730.
At the moment it has no sdhc card, only a blank piece of plastic in the slot. A new sdhc card has been acquired.
All the current system and maps must be on the internal memory. If I put a new bootloader and Navcore onto the sdhc card do I need to delete all the internal memory before I insert the new sdhc card and switch the unit on? or will the new Navcore update the old one
I intend to use the:
