660 shuts down after boot

Post by Nashcat »

My 660 has started locking up and shutting down, during boot up. It has a new battery, that’s fully charged. This started happening, not long after I updated everything, on the Garmin site.

If I pull the SD card, it will boot, just fine, and show my location on the screen. But, without the SD card, I can’t enter an address without getting a message that it can’t find any data.

I guess I need to hook it to the computer to look at the internal files, as well as the SD card files.

Any suggestions?

Thanks,
John

You might try reformatting your SD card. Be sure and copy everything on your SD to a temp folder on your computer before you format, so you can put it all back after the format. Danham has suggested sdcard.org formatter as a good method for reformatting rather than using standard format on your computer.

I was having lockup problems almost every time I used the unit. I deleted the maps from the card and put just the lower 48 states, which currently fits, in the internal memory. Since then I have had no problems. I believe the 660 was having problems reading map information from the card. I then reformatted my card and put my music back on it. This seemed to help load the music faster, making boot up faster. Not fast, just faster. I may be able to put the maps back on the card since the reformat, but it is working now so I'll keep it as it is.

There is a post here about a "preferred" SD Card format utility. I have not tired it yet. Just more information for you.
