So far, other than the terrible manual, this is a great system. One question, there is a warning that comes up saying my battery is critically low. This happens almost all the time. I use the cig lighter charger and the one for my USB port on my pc. Still the same issue. Any thoughts? HELP!
Navman's batteries are worst among those I used.
Maybe you need to charge your unit from mains supply rather than USB or in car. USB charger only gives you 10 mA to 30 mA charging power and cig lighter only charge at about 50 to 100 mA. Mains supply will normally charge more than 300mA. Some faster charger can reach 500mA. You can easily see the different.
Beside that, there is nothing you can do for Navman's battery.
Agree with previous comments . Having serious trouble because when the battery goes flat memory is lost.. Can not find a replacement battery for my MYESCAPE III gps. great unit but now useless unless I can find a new battery
