Hi folks, great forum you have - anyway, newbie straight in with a problem. (Hopefully I'll be of help here one day myself).
I've had an SP2820 for nearly 3 years now, and must say, it's been absolutely faultless, until last week.
I now seem to have 2 issues, although the second maybe a function of the first.
It seems to struggle getting a satellite signal, sometimes not even indicating it has a signal from a single satellite, let alone enough to get a relaible fix. This happens in both cars I use it in - so I know it's not a problem from the likes of heated windscreens etc... as it's been reliable in both since I've had it.
I also use it sometimes hooked up to a laptop or netbook, via the usb, to use the position fix the 2820 has for use in another mapping program (UK Memory Map) running on the laptop or netbook.
However, it has taken to dropping the signal to the laptop or netbook, even though both the 2820 and the laptop know they are still connected to each other.
To recover from this, I have to reboot the 2820 and re-start Memory Map.
Sometimes (even when the 2820 has hold of a decent set of satellite signls), the signal to the laptop will hold OK for an hour or so, before dropping, other times, it will only last a few minutes.
I have tried reloading the latest firmware (ver 4.40), incase it had become corrupt, but this didn't resolve either issue.
And the correct usb drivers are loaded in both the laptop and the netbook.
