If you used an SD card for the W&C Euro map, did you also use Navcore 8 on the card and/or patch the ttsystem file on the SD card too?

Remember, apart from the x20 series, the unit can only read/run either internal memory if it has it OR from SD card so BOTH need everything installed incl patched ttsystem file etc.
