Hi,
I'm experiencing a similar problem to you mphayvanh. The only difference is that TomTom randomly starts up rather than trying to install itself.
Touching anything in the 2577 folder produces the "No Maps Found" message.
I have a feeling that mine might be starting up randomly because of the well documented "disappearing SD/CF Card" problem caused by Activesync. I'm assuming that when the card 'vanishes' and then 're-appears' the Axim behaves as if I've taken the card out and re-inserted it, thus starting TomTom. I'm hoping I've fixed this using the hack described
here.
However, to be on the safe side, I would like to find a way to stop TomTom automatically running when I remove/re-insert the SD card anyway, because it's still a pain even without the Activesync problems.
I'd be interested to know if you have any luck with this.
All the best
Jon
