SD card not seen till soft reset - N35

Hi all

I'm having a little difficulty with my back up disc with TomTom (1GB San Disk).

After starting the app (TomTom) I get the splash screen for safety . . and no maps!

I've reformatted the disc and copied over the files again but the problem persists. Until I do a soft reset.

No problems with supplied disc.

I must say the WMA & WMV on the Acer is good and overall I have to say that that considering the price the functionality far outweighs the the "wee" problem with the SD card.

Anyone out there had or resolved the same issue?

Cheers in advance!
