HEMA HN7 charging

Hi all,
Just bought a new Hema Nav system. It doesn't hold a charge. Wondering if any one got the same problem?
Thanks for your input in advance

hi rocknut,
there is a section in the user book page 13  on how to get first initial charge  ,
check to see if light chnged from red to green to indicate full charge  if not  either your charger is not working properly  or computer  usb port is not right one.
get a multi meter and see if you get a output on charge lead.
hope this helps

Hi Lone Wolf XLIX
Thanks for that. Send a mail to Hema too, They suggested that the car charger may be faulty. The unit seems to keep the charge if using the USB connection. Going to find out tomorrow how long the charge will last by driving to a location using the Hema. Hoping to find a few bits of yellow or at least one. Have a good weekend.
Cheers
Ray
