Track change controls on steering not working????

[Squeeguk]

My RNS510 F has been working perfectly since I installed it until this last week when it froze on me. I rebooted the system and all seems fine excepting that my track up and down buttons on the wheel no longer change the tracks on my RNS. I tried switching off and rebooting and still nothing.

Anybody got any ideas?

As an aside, all the buttons on my MFSW work except for the phone symbol button. What is this supposed to do and what should I be looking at to getting this working?

My up / down buttons do not work either, but I think Ive changed some coding that may have affected them.
The phone button is for the bluetooth kit so you can make or accept calls when your phone is connected.

Thanks for the response. I was starting to lose hope, lol.

My buttons started working again, but the phone button does not work, no matter what coding I use and I do have the OEM BT kit, so a bit lost there.
