Battery capacity degrades at low temperatures and over the life of the system.
In the event that the vehicle power port is unusable, such as a blown fuse, or if required for
an airport security check, the 750M can be used solely from a new, fully charged Battery for
periods up to 1 hour. To do so, simply slide the Battery Charger switch to ‘BATTERY’. Be
certain to slide the Battery Charger switch back to ‘OFF’ or ‘AUTO’ when finished to avoid
depleting the Battery.
Map Area Switching
The 750M incorporates a feature called ‘Auto Map Switching’. When the 750M is transported
from one Map Area to another, it will automatically sense the change and then switch to the
correct Map Area within several minutes if other Map Areas have been purchased and
unlocked. In the event that the 750
M needs to be manually switched to a different Map Area, it
can be easily done as follows:
Step 1: Refer to Map Area illustration on page 27.
Step 2: Press OPTION to arrive at the ‘User Options’ screen.
Step 3: Scroll to the ‘Configuration’ icon, press ENTER.
Step 4: Scroll to ‘Map Selection’, press ENTER.
Step 5: Scroll to the desired Map Area and confirm that map is unlocked. If not, call
Magellan Customer Service at 1-877-4CARNAV (1-877-422-7628), otherwise, press
ENTER.
Step 6: The 750M will ask “Confirm Map Change”. Highlight ‘Yes’, press ENTER.
The 750M will power down to save this change and will restart automatically. Select desired
user and continue enjoying the 750M.
