Hi and thanks for the replies.
I will try 30 seconds. I've only held the power button for maybe 10 seconds...so I'll try 30 secs.
I measured the voltage of the battery when I opened and disconnected it from the board. It measured approx 3.6v so I assume thats enough for a li-ion battery to run for a while. Not sure what the cut-off voltage for the power up of the Garmin is...maybe 3.2v??
Will I have to charge using the car charger? I have only tried charging with the usb connected to the pc.
Thanks all
N
