If so have you tried reformatting internal memory using RMPrepUSB as you said you might try a few days ago?
3490->3790 I have done it once using RMPrepUSB, but have copied old files structure from archive copy made 2011. Unfortunately this week have no enough free time to make it with WebUpdater i.e. to start from the very beginning. After returning to 3790 I have never reach 3 m. accuracy. Hot fix is OK and first 5 minutes or so unit locks on road well. But then.... it is a complete mess. Of course unit has it's good times, but bad times are much more and make it totally unreliable. I even started to think that it might be the case that unit's antenna is broken. I have dropped unit several times . This weekend I will try and will report accordingly.
