I have an old Garmin Pilot III that I use with Navbox Proplan 5. Due to its age, it has a serial port connection, so my Windows 7 64 bit machine has a USB to Serial adapter running as COM-5.

Navbox uploads fine, so I know the hardware aspect is functional.

I have tried the Skydemon eval, but when I try and upload the route to the Garmin, (after clearing any existing routes on it), the name of the route goes over, but nothing else - there is no route information and no waypoints.

I'm either missing something obvious or there is a compatibility issue with the Garmin. The unit was replaced by Garmin in the last year after the old one developed a fault so it has the latest firmware.

Are there any other owners of a Pilot III that are successfully uploading to their GPS from Skydemon, and if so, did you have any problems initially?

Any suggestions welcome!

Cheers

SD doesn’t seem to work with quite a few Garmin units – fine with my 96C but not my MAP 60 for instance (communicates no problems but data transfer is truncated). I think they may be correcting this “with a tweak of the GPX code” the new version 2.3?



A workaround I have been using is to save the route as a GPX file, open it in EASYGPS (free ware) and then transfer it to the Garmin. Although they might perhaps not be too keen to support the competition – it would still be very useful to be able to transfer routes directly in to any Garmin.

Thank you for the information about EasyGPS - this does indeed appear to offer a way of interfacing SD with older Garmin devices. Navbox still supports my Garmin without needing a kludge to communicate so will remain my primary planning software for the moment.
