Even on repaired N97, there is a tendency to lose the satellite fix with the unit heats up.

This running hot/loss-of-fix seems to occur:

1. Immediately after being on a mains charger
2. During long trips where GPS display is set for continuously on
3. Charging on car charger while using GPS

Looks like an engineering error in the design of the circuit's heat rejection and/or lack of temperature compensation with regard to GPS processing.

Immediate workaround is to use an external Bluetooth GPS.

No wonder Nokia lists the Nokia Bluetooth GPS Module LD-4W in the Accessories listing for the N97!
