Yes, it is, thank you, but my five year old iPAQ 2210 runs a version of Windows Mobile that both TT6 and my SysOnChip CF Card antenna won't run on and which can't be hacked to do so.
Given that I now have a Blackberry that meets my mobile computing needs, all the PDA gets used for is GPS in car and on motorbike, so it's time to move on and buy something better suited to these specific tasks.
