What is the PIN Code?
When connecting to a Bluetooth adapter, you may be asked to type a PIN code. If you are asked to enter the PIN code,
type four zeros (
0000
).
The LEDs Do Not Turn On
If the LEDs do not turn on, ensure the battery is fully charged. If the LEDs still will not turn on, make sure the battery is
not inserted upside down. The contacts on the battery should line up with the contacts on the device.
The Battery Will Not Hold a Charge
The Li-ion battery is designed to last for 300-500 uses (depending on environmental conditions). Please visit www.
delorme.com to purchase a replacement.
How Do I Know Which COM Port to Use?

which COM port is associated with the
Earthmate GPS BT-20

select
Bluetooth
from the Port drop-down list.

Charging the Battery
The
Earthmate GPS BT-20
comes equipped with a rechargeable, Lithium-Ion battery. The battery charges when the
device is connected via USB or the vehicle power point adapter.
Troubleshooting
First Things to Check:
• Does the
Earthmate GPS BT-20
have a clear view of the sky? Buildings, mountains, and heavy foliage may
block your satellite reception.
• Is your mapping software running properly without the
Earthmate GPS BT-20
?
• Have you tried disconnecting and then reconnecting the device?
Why Won’t the Device Acquire or Maintain a 3-D fix?
If the device cannot acquire or maintain a 3-D fix, it may be because the device’s view of satellites is obstructed. Try
repositioning the device to another location, such as in the middle or corner of the dashboard. You can check the signal
strength at various locations in your vehicle using the steps below.
1. Open your DeLorme mapping application.
2. Click the
GPS
tab.
3. Click
Start GPS
(if the device has not already been started).
4. Click the
Status
subtab.
5. Under Satellite Listing, examine the values listed in the dB (decibel) column. To acquire a 3-D fix, at least one of
the values should be greater than 40, some of the values might be in the 30s, and a few might be in the 20s. If
your device is not receiving such values in its current position, move the device to another location, such as
another place on the dashboard, until it reaches those values.
Note:
If you cannot obtain a 3-D fix anywhere on your dashboard but can obtain a 3-D fix outside of your vehicle, it may
be because you have a heated/metallic-coated windshield that interferes with satellite signal. Heated/metallic-coated
windshields are common in luxury vehicles. Try placing the Earthmate GPS BT-20 behind the rear-view mirror or in the
rear windshield of your vehicle.
