Have just got this set up and pretty pleased. However, I bought a Fujitsu 1GB SD Card to add the european maps on it. Whenever I add more than 1 map, the whole card currupts and I have to reformat it. It seems to work fine with other media, has anyone had the same issue or is their a solution. I have been adding the country maps to seperate SD cards to get around this issue, but I would like the all on one.

Well, 2 guesses.....

1. It's a faulty SD card.

2. Maybe the PDA doesn't support 1GB cards ? Have you checked with HP to see if there is a "BIOS" update for your PDA ? Beware though, because uploading a new BIOS will erase everything from the main memory of your PDA.

I have two maps on a 256mB card without problem if that helps any. Seems to support Nick_UKs suggestions.

I use TomTom 3 on an XDA IIi with a 1gb SD card, I find it's reaaaally slow looking up addresses etc.

I wondered whether 1gb cards are just inherently slower and this was causing TomTom problems?

All
thanks for your advice. Just got back from a trip and great to see.
My wifes been using the SD in a camera and we have had no problems, likewise the 1GB card is fine with 1 country on and other info, it just appears to be when multiple maps from Tom Tom are on it then**** it goes. I will check with HP when I get back again, on the bios issue. Is there anyway to backup all appointments etc or will tehse just sync back from your pc? - sorry I'm new to PDA's if this is a stupid question.
