I am trying out a Nuvi 65LM on a motorcycle. Original Garmin socket mounting. Power is from the motorcycle's battery, via a 12 volt to 5 volt USB adaptor, & it with the Garmin cord works fine.
After something from 3/4 to 1-1/2 hours, the charging quits, then the GPS battery runs down fairly quickly since it has to be set for rather high brightness to see it......but the power adaptor is OK.
Garmin's literature implies that at or above 113 degrees F. inside the 65LM, it cannot be charged. I suspect a temperature sensitive circuit was used for to protect the battery from having a serious problem.
I think the answer MIGHT be to glue bright aluminum foil or insulated aluminum foil on the entire rear of the unit so the sun's rays are reflected. However, I don't know where the antenna inside the case is located, and don't want to reduce the sensitivity to the satellite's signals very much.
Anyone have this problem and solved it....OR?
thx
Rob
