Hello, would appreciate some help if you can.
I have a Compaq iPAQ 3950 which I use for sat nav in a iPAQ Navman GPS V2
OA (GPS 3450 Voice) sleeve. Until recently everything was fine and I was
using Navman 3450 with SmartST Professional navigation software for ipAQ
Pocket PC with no problem.
I thought I'd try Tom Tom 3 in place of the Navman because it is compatible
with camera location software.
Problems started when I uninstalled the Navman programme and maps from the
Kingston CF/256 Compact Flash Card in the expansion slot of the sleeve.
Since then every time I start the iPAQ when it's in the sleeve the
following messages come up.
"Unrecognised Card"
"Enter the name of the device driver for the card. For information, see the
card manufacturer's do***entation".
"Unknown Card in Socket 2".

I did not buy units from new so I do not have any do***entation for flash
card, I have tried all manufacturer's web sites with no joy and certainly
no help from any of them.

If anyone can help it would be appreciated.
