What to do when you forget your Garmin PIN.

You have Garmin Lock activated on your nuvi: there are only two ways you can unlock it.

1. Enter the PIN code (but you clearly don't have it or you wouldn't be reading this).

2. Take the unit to the Security Location you chose when activating Garmin Lock: it will then unlock without the PIN code and you can then either reset the PIN or disable Garmin Lock. The Security Location should not be the owner's home address, but many owners ignore this recommendation. Many owners choose their workplace or a close friend or relatives address for this purpose.

If neither option works then your unit is useless unless you send it to Garmin with proof of purchase. Garmin charge for the service and if your maps are not up to date then it's really a waste of money as the investment would be better spent on a new unit with current mapping.

I hope that you manage to either fix your problem using my advice or at least can decide whether to abandon the unit and buy another.
