I've got an Acer N35, which was working fine yesterday morning. Went to see a customer and when I switched it back on, it couldn't find a signal. I assumed it was because I was in a valley so didn't worry too much. But it's still not able to recieve any signal at home, where I know it previously gets a full signal. So, I've performed a soft reset, which didn't work, a hard reset, changed the sd card and re-installed the Destinator software (still no joy). I then did another soft and hard reset but nothing. The PDA has been on since 8.30 and it's not picked up a signal. There's a blue GPS LED indicator that flashes - that's working.
