Hello.
I own a bundle HP/TomTom iPAQ 1940h and GPS Bluetooth.

My questions regard the batteries of both the devices, the best way to ensure them a long life.

When I use the Navigator in my car, is it correct to connect the iPAQ/GPS to the car's power supply EVERY TIME?
Or is it better to use their built-in batteries until they're drained?


Thank you very much.

I don't have a 1940/45 (only a 1930, without the bluetooth), but I beleive it's customary to run the devices from car power whenever you can. The batteries don't need to be drainied like old nicads to keep peak functionality.

Regards,
Craig.
