GPS Repair Problems? Ask a GPS Technician for Answers ASAP
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That sounds like a defective product... and it is almost surely within its warranty still.
For the warranty terms on Sureshot 750 devices:
which would seem to be either 1 year or 2 years from purchase date, so yours should be covered. That page has the warranty return procedure for SureShot GPS devices on it.
For other SureShot contact information see http://www.sureshotgps.com/customercare.php
the email and phone links at the bottom of that page.
I would say, the symptoms you report are those of device failure within warranty, more specifically a failure in the battery and/or the charging and power systems of the device and/or its charger. Returning it to SureShot GPS for free-within-warranty repair is fully justified.
Good luck with it.
