HP ipaq with navtec gps software and sd card fails
Ok, nice job Robert,
I'm posting your solution here to remove it from the unsolved problems list.
Solution by Robert:
This problem was finally resolved as a corrupted map file on the SD memory card in the hp ipaq 5550. Solution was to reformat the memory card using fat32 memory format. I used a SD memory card slot on my laptop and right click the drive letter and select format to format the memory card. After that, I reloaded map files to the memory card and all was OK. Note that previously I had loaded map files on the memory card successfully but that was not good enough. A reformat of the memory card was apparently needed.
I had also previously tried a hard full reset of the ipaq by pressing and holding the lower two buttons (calendar and itask) while holding in the reset button with the stylus for 5 seconds and resynced my contacts and reloaded the gps software, but this was to no avail. Try the re-format.
