Hi Stéphane,
sorry for the delay in the answer, but monitoring this forum was broken for me.
I don't know anything about the Holux GPSport 245, unfortunately I don't have one. If you can please post again a binary file I can check it (the link you provided seems now broken).
Hello !
Is the Holux GPSport 245 with the new MTK 3318 is planned to be supported.
I upload a bin file if it's useful for you : http://www.stephane-brunner.ch/2009-07-30-16-29.bin .
If i can help you it's possible ;-)
CU
Stéphane.
