Bluetooth adapters and Aux /in headphone plugs are not support by the screen and controls on the Vic. Only the volume will work. Software was written for iPhone and ipods since their std output supports this information.
Bluetooth only supports this IF the receiving unit, has built in Bluetooth, otherwise the devices for receiving data only pass audio through, and the Vic bike simple sees the music.
This is common since you are using BT as a work around for not using an audio cable.
Most people are using the BT device and simply mounting their phones on the handlebars to see music, incoming calls, GPS.....
