Question about Garmin Nuvi 660 GPS Receiver
When I charge my Garmin nuvi 750 it will not display the maps. Using car charger.
I learned that with the unit off - hold the on button down - don't release it. A PRE-BOOT MODE message will appear at the bottom and may flash. Continue holding down the start button. The first time I did it a series of dots came on the screen and I was instructed to touch each one. After that it started as normal. I plugged into a wall charger and but git the pc and nuvi icons again. I repeated the process - holding the on button on and let the PRE-BOOT MODE appear and kept holding but this time a different message came on and then the PRE-BOOT MODE appeared again. I let it go and took the unit to my car and plugged it into the Garmin car charger and it worked as it used to - normal. However, when I plugged it back in the house to the wall charged I got the pc and nuvi icon again. It appears that I am using the wrong wall charger as a previous writes stated. But the nuvi still worked in the car plugged into the nuvi charger. I hope this helps.
