The units is a few months old, was used 2 days ago on a long journey with no problems , on using yesterday on a shorter journey after less than 20 minutes into the journey the unit went blank and switched off , it would not switch back on , the journey continued with the unit plugged in to the car charger, it was tried after a further 30 mins and no response , it was then plugged into a computer for 2 hours and still no response, then back at home was plugged into a charger and left overnight , least 12 hrs , still no response
Thanks , I have just tried this, while holding the button , the Garmin name appeared, then disappeared a number of times , but did not power up
as soon as the power button is pressed the name appears ,after a couple of seconds it disappears again wether the button is held or released, on pressing the button again it comes back on , but only for a couple of seconds then goes off again
and follow the instructions there.
