Hi,
My BU-353 works well and reliable under Windows XP 32 for about two years.
Now I migrated my CarPC setup to Vista 64. No success yet. See below:
Mainboard Asrock ALiveNF7G-FullHD R3.0
CPU AMD Athlon 64 x2 4850e
2 GB RAM
The BU-353 is hooked up via a 7-port powerd hub by Trust.
Two different programs TTQV4 and Igo_PC say that they can find a GPS receiver. Both programs say that no coordinates are received.
Here is an excerpt of NMEA data that I logged:

The GPRMC strings include V for void and along with it no coordinates are sent.
The BU-353 shows correctly as a Prolific COM port emulator in the device manager. I set the baud rate to 4800 as usual. I tried without FIFO enabled and disabled to no avail.
The reception of the BU-353 was good under Windows XP so I can't imagine it has no reception now.
Please help.
Thanks for reading
