8.8) Trouble locking onto satellites
There are several issues to check for:
1. When you purchased your nav unit, there was no satellite data stored inside. Your unit will
be slow to acquire satellites until it has an opportunity to store satellite data. To let it store
satellite data, simply let it run for at least 15 minutes AFTER it has locked onto satellites.
After that, it should find satellites much faster.
2. Although your nav unit is very sensitive, your installation may not allow enough of the
satellite signal to reach the unit. This can occur if the unit is not installed at the windshield.
For best satellite reception, mount your unit at the windshield. You can also order the
optional external antenna, part number EXT GPS ANT. Click
for info.
3. The antenna is located at the top of your nav unit. During installation, please arrange the
mounting bracket so that it does not block the top of your unit.
