got WM5 running foe few days on X50V
and already saw 3 times the CF card vanish, i have to soft reset to see it again
is this another bug ? or theres some solution for now ?

i have the same problem bro

Yes, this is a known bug. I didn't update to WM 5.0 yet but lot of people are having these issues. Search the forums. If I don't remember it wrong, leaving Bluetooth "ON" at all times solved this problem.

I do leave the BT on all the time since i use navigation software, but thats another problem, sometimes the BT switches it self off, so have to turn it on again
guess its those new OS problems
will be solved in the future

At least some of you can get the Cf card to come back with a soft rest . I have an X 51 Updated with A 04( second replacement waiting on my thrird to be delivered tomorrow ) Everytime I put my CF card in the slot it will ask me if I want to format. Does not matter what I choose it will not show up. It shows up when I insert in my San Disk card reader on my home computer , but not inh the Axim. I even tried a hrad reset for the heck of it, still had no effect on the card showing up. I have a SD card in there that shows up in my device. When I received the X 51 it had A 03 on it and I updated it to A 04 maybe I should have tried with A 03 first
