I got my 4 GB from Grassroots PC on ebay. I have had it fail 2x so far by losing it's format (1st time 2 days, 2nd time 3 days).

I made 2 changes since the first two trys, loaded VC 1.6, and Weatherpanel on the main memory, and also did NOT load Hubdog (RSS Podcasting SW) on the card. So far I am sitting at 3.3 GB for over 10 days with no issues.

I do have issues with Inav and slow voices...I will be looking for the patch that fixes this soon.

My theory is that Hubdog writes the card before it shuts down.....the card/PPC is slow to write to the card and it might not write to the card fast enough before it shuts down and corrupts the card after a while. (just speculation)

I am going to add Hubdog back on tonight and see what happens.
