Thread: problem, format nuvi 660

I can't see how your problem may be related to the GTM fw. Your unit is traffic capable but the GTM fw is only used when a traffic receiver is connected. Did you reload the current (unit) fw and reset as i suggested?

Hi Neil I'm glad you answered
Just do as you're told. I erase all user data, reinstall fw with WebUpdater again erase all user data, launched device made ​​a circle around the buliding and the result is the same, no voice no navigation.

new moments
I found something interesting, if only the basemap installed and start to navigate, there is a voice assistant, but the route is so determined to go hundreds of miles around insted few miles. If I choose another item to navigate then no voice and no recalculation assistant but well-defined routes. The third point to navigate behave the same way as the first, but it has a voice routes hundreds miles around. I think that the basic problem in the handling of map and recalculating new routes.On Inventory screen basemap stil calculates, never stops and says pass.

Also I found NAND test page checksum faild, whether it can affect the operation of the device.
When I worked FAT32 format memory I did with Windows7. There are several options cluster sizes for FAT32, I did with 4KB. What is the cluster sizes for nuvi660, 512 bit or 1KB or 2KB or another? please help
