I am posting a reply from zorrogps may be once their version 3 is released next week I will give it a try -- once I get Firmware 2.0 SD card from pioneer!!. The maps cost by itself is very low...
"Hi,
Thank you for your email. ZorroGPS runs now only on Windows Mobile. We also never try to run AVIC F500 bt. You could try next week when the PND Release version 3 is available.
Hope to read you soon.
Thanks,"
