I have a 2001 Yamaha XVZ13TF .
This winter I installed a Garmin Zumo XT on the bike. The Zumo when connected to my iPhone’s Bluetooth was useful for the mapping app on the Zumo, but not for any audio, YET. I then added a Bluetooth receiver to the bike which also connects to the Zumo. Now I can listen to my iPhones Music, SiriusXM, iHeartRadio, etc. thru the bikes headset or speakers. Adding the Bluetooth receiver also allowed me to receive and play, or read, text messages and voicemails on the Zumo. Without the Bluetooth receiver the Zumo will not accept these messages from the iPhone. I was not particularly interested in receiving messages as it is a distraction, but it is quite simple to click the notification and play them.
To install the Bluetooth receiver I removed the front of the fairing and then unplugged the aux jack cable near the cassette player from the receiver amplifier. I then plugged the Bluetooth adapter into the aux input of the receiver, no adapters needed, very simple. For power I spliced the Bluetooth power wires into the 12v aux power port in the fairing. The adapter I purchased is an “NVX Universal Bluetooth Adapter - Waterproof Audio Receiver - Auto, Marine”.
Spring has finally arrived and I took my first ride of the year with the new Garmin and Bluetooth and they worked wonderfully.
