Tested this product, but it doesn't work on every PDA with SDIO slot and WM5.0 I tried it with.
Installed the driver, but both the GPS and the card slot refuse to do anything.
The MicroSD (tried several) won't show in the file system, as it prompts for formatting after inserting in the iPAQ hx4700. When I press OK, nothing happens and the card won't show up in the Explorer as well.
The GPS shows up in the GPS list in TomTom Navigator 5 and 6, but when I select it, the program keeps looking for a fix, without success, even after 1 hour.
I tried lots and lots of SDIO devices, but none of them seem to work. It might be a faulty sample I received from Spectec, but until that isn't sure, I say: damn what a 'pain product'.
