Mine is doing the same thing. I replaced the battery thinking that was the problem but it still does the same thing. The speaker was cutting out prior to this as well. Any ideas on how to fix it. All it does is cycle on to show Garmin on the screen, beeps and shuts down then restarts again doing the same thing over and over.
I'm having the same problem with my Garmin nuvi255w and looks like no answers on this fix yet? Garmin says they won't fix this model so I am looking at Nabilselectronics.com to see if they can help and was wondering if any one else has heard of em?
Has anyone found a solution? I charged my 765 the other day with my Garmin AC charger. After a few hours I checked the screen to see if it displayed charging complete. It did not, and the Nuvi 765 as well as charger were quite warm! Now the 765 only flickers when I try to turn it on. This is very frustrating because the unit has the newest updates, and was working fine before this.
"I had the exact same problem, replaced the battery, 3 times as I thought the new batteries might all be duff…..I think the answer is: Never buy Garmin.
I want a Sat-Nav, but one designed so I can easily replace a battery in a battery compartment & I don’t have to void a warrenty or buy a new Sat-Nav every time the battery is exhausted? Are there any such makes out there?"
