 Usage:
A. For PDA with built-in Bluetooth
1. Turn on the power switch in BTGP38-Plus
2. Please refer to the user manual of PDA and make the Bluetooth of PDA
connect to the BTGP38-Plus. Some PDAs may need the Bluetooth
passkey, the passkey is “0000”.
3. Check the number of COM port used by Bluetooth.
4. Run the suitable mapping/navigation software and select the correct COM port
& baud rate: 9600

B. For PDA with Bluetooth Compact Flash card
1. Turn on the power switch in HGR38W.
2. Please refer to the user manual of Bluetooth Compact Flash card to make it
connect to the BTGP38-Plus. Some Bluetooth devices may need the Bluetooth
passkey, the passkey is “0000”.
