GPS Data Logger Software - BT747

HI！

I use bt747 deaktop BT747_2.0.1_full version connect my Holux M-1000C successfully，I want chang  Holux M-1000C’ GPGSA & GPGSV frequency in advanced device configuration（Flash configuration）,because it's GPGSA & GPGSV frequency is 1 time/1 sec.I used 1000C connect my cellphone Nokia 5320（S60 V3）successfully,can receive signal,but in Route 66,when at navigation mode it can't display direction arrow.I think that because of 1000c's GPGSA & GPGSV frequency is 5 times/1 sec,but Route 66's 1 time/1 sec.1000C and Route 66 can't sync.

Please give me a hand deal this problem,my Holux M-1000C firmware version is 1.30.Could I edit firmware ?

Thanks!
