Device Compatibility

Most Bluetooth devices (such as iPhone 3G/3GS/4/4S, iPod Touch 3rd/4th 
generations, and Android phones) are compatible with the BT35.  However, 
USA SPEC does not guarantee that all Bluetooth devices are compatible.  For a 
current list of compatible devices, please refer to our website www.usaspec.com

Pairing the Bluetooth Device

Steps to Pair Your Bluetooth Device

Step 1:  After your BT35 has been properly installed into your vehicle, 

turn on the ignition and the radio.

Step 2:  Select the CD or SAT button on your radio (this will depend on what
 

DIP switch setting the BT35 is on). This will put the radio in 
Bluetooth mode and you should see either 

Figure 1

 or 

Figure 2

. If

you have a text button on your radio, you may have to push the text
button a few times to get to this screen.

Step 3:  Make sure your device’s Bluetooth setting is turned “on” on your

device and select “search for new devices”. (Refer to your
device’s owner’s manual). BT35 should show as one of the options. 

Step 4: Select the BT35 to pair it with your device. If prompted to enter a

code (some devices may not require you to do so), enter “0000”.
Pairing may take up to 20 sec. When you are connected, you will
hear the voice prompt “

Connected

”.

Once paired, the BT35 will automatically recognize and connect your Bluetooth 
device whenever you turn on your ignition.  

Additional Pairing Information

Some devices may require additional steps while pairing. Refer to your 
device’s owner’s manual.

Ÿ

The BT35 can be paired with up to 8 devices, but will only connect to 1 
device at a time.

On some vehicles, the BT35 will automatically turn on your radio when you 
start the ignition in order to connect with your device.
