Garmin 67/68 US to Garmin 67 APAC

Hi Guys ,

Is there anyone done making conversion of Nuvi 67/68 US to 67 APAC version successfully ?
When I tried to flash it with updater program after converting it to be RGN File , it's showing system software missing , and it's not booting .

I just checked and see that the Mfn PN is not the same

For 67/68 US , PN is 010-01399-04
For 67 APAC , PN is 010-01399-70

And also once I tried to open the file on the RGNTools , the HW ID is not the same

HWID for 67/68 US on 4.40 Firmware is 2088
HWID For 67 APAC on 2.30 Firmware is 2298

Is there anyway , we can do to convert it to be APAC version ??

Please help to advise and comment .
Thank you very much .
George
