yes and no.
- the volume is provided by the audio system so you will always be able to use the volume buttons.
- neither the AUX nor FM transmitter extension modules support next /prev buttons. due to this disadvantages there is an another option:
- - prev button alternative: dial 444
- - next button alternative: dial 666
- - play/pause button alternative: dial 555 |
Do you have access to the CAN bus messages?
If so, you could read the UP and DOWN buttons on the steering wheel, as they are on the CAN bus....
I suspect however that you connect the the phone modem slot and thus follow the standard phone interface command set and have no control over what keys you can use.... other than phone keypad keys....
