I have worked with many different GPS modules (Byonics, Argent Data, and many chip modules) in a very wide variety of environments.
I have yet to have one fail due to heat or cold - not saying it wasn't the cause, just that I haven't experienced it.
The only one I that has failed for me was when the 5V regulator failed and it received 12V (not a jumper mistake, the regulator failed).
Fried one of my TT4 units with it.
I agree with other posts on 2 points:
1.? Not worth trying to fix a GPS module.? Replacement is cheaper than repair.
2.? There is a good possibility you can connect to it through serial interface and see if it is totally failed, or some other issue.
? ? ?I can't speak to the Byonics unit, but I have experienced an unexplained configuration change.?
? ? ?One big one was baud rate.? Of course it changed to some factory default.? I think the Byonics units were at the factor default.
