Question about Garmin Nuvi 660 GPS Receiver
This is a common problem caused by a certain style of touchscreen being used. There is conductive silver ink/paint borders around the outside of the touchscreen that fracture
due to heat. The touchscreen can not be repaired and must be replaced with a style that does not have this issue. Please see this link for more information
as there is just too much info to copy and paste here.
