NAVIGON 7100 provides Bluetooth® pairing with your handset for easy hands-free calling. Every handset is different, so it's best to consult your handset's manual to determine how to search and pair it with external devices. In general, you'll need to prompt your handset to search for and sync with external devices. Your handset will return with a list of external devices it has found. Select NAVIGON 7100 from this list. The NAVIGON 7100 automatically prompts you to enter a password; enter 0000 and touch the green arrow. In the event your handset asks you to re-confirm whether you want to connect to your NAVIGON 7100, select 'yes.'
