It's probably died. My BT-77 GPS receiver seems to have suddenly become unable to resolve a fix. Although it can "see" satellites (I've seen it with 7 in view but more usually its somewhere between 3 and 5) it seems to sit there saying "yep, there's some satellites up there" but can no longer work out where it is. This started about a week ago. There is only one button - the on/off button - on the receiver and I'm wondering if it's possible to "reboot" the thing by some magic keypress on this button. Sort of switch it on and then give four short on/off button presses in quick succession. Or am I going to have to shell out for a new one?
I've put this in the GPS-cellphone group too, but maybe someone here knows? TIA for any help, Steve
