Reading maps from SD card ?

[Markus]

Hello

I would be very greatful for some helps regarding running Tom Tom maps from and SD card.

I have TomTom 2 bluetooth running on my ipaq h1940 with and impact 128mb SD card.

When I try and search for an address from a map larger than 16mb on my SD card the TomTom programe just switches off and I get back to the ipaq front screen. I can run 32mb maps within the ipaq's ram with no problems.

The card is formated with fat16 with 16kb clusters. As an experiment I tried 2kb clusters but with no luck.

Can anyone shed any light or reccommend from experience a good quality SD card that will allow me to run large maps 32mb+.

Any help would be much appreciated !!

Regards

Had a similar problem on my Viewsonic V37... solution was 4 stages...

Stage 1: get an SD card that actually worked reliably... eventually ended up with a Panasonic one after testing out 5 or 6 different ones (usual suspects... Lexar, Sandisk, Fuji, PNY... mostly Chinese manufacturer, Panasonic is Japan). That's a well known prob with SD cards. Only way to really check them out is to write bulk files directly from PC to USB reader then check you can read all the files from the card in the PPC- i used MP3 and MPEG files as these stress the card access mechanisms well. Most of the cards formatted fine in the PPC and seemed to work but wouldn't actually let you read files properly. Also bulk xfr via activesync is slooooowwwww and i suspect not all that reliable....

Stage 2 was to install TomTom via activesync and install maps to SD card using USB reader, put SD Card in PPC and soft reset. Even then TomTom wouldn't find the maps!

Stage 3... use Activesync to install small map to main memory to allow TomTom to start properly... then use Navigator Properties to change map set to those on the SD Card... it finds them ok on SD card after accessing a map on internal memory. I have no idea why this works, nor did TomTom, but it does...

Stage 4: Once thats done, you can remove the maps from local memory and its fine after that.

Hope that helps

Many thanks ! I will give it a try.

I have ordered a Sandisk ultra II 256 mb card. Panasonic are part of sandisk so hopefuly I will get the same results that you did.

Please forgive my stupid question -- I feel so dumb for asking: how do you remove a map after you have installed it?

Thanks a lot for any advice -- this forum is great, definitely the most informative place that I have seen for GPS and PDA!

On the PDA, click on start, programs, file explorer, directly below where it says file explorer (in grey) tap there change to my device, select storage card, click and hold on the file select delete.

This can also be done via PC if connected, click on my computer, mobile device, my pocket pc (or whatever u called your PDA), storage card.
