Code forgot my pin

I left my unit in van but think you can go to your register place and reset it or something
will need to look at instructions tomorrow
don't set my password as it shuts down every time I stop my van and a pain in backside to enter every time.
anyone know where there are any free europe maps for the 660?
also is the fm transmitter option only available from factory?
anyone know how I can reprogramme the doris to warn me of speed traps, but without step by step instructions?
also I have the traffic information system on mine, but doesn't seem that reliable, is this the norm?

If you need to unlock the unit, the only options are to enter the correct PIN number, take the unit to the location where the PIN was entered, or send the unit back to Garmin.

I inherited my fathers Garmin nuvi, he purchased it 2 years ago at a Costo possible in California, Mom is not sure as they were full time traveling the past 4 years in their 5th wheel. We could not find a manual and don't know the pin, I don't want to send it back to Garmin is there a customer service number where someone can talk me through setting it up so I can use it.
