You wont see phone menu on red dash unless you fit polar fis bluetooth or polar fis advance adapter. New bluetooth modules don't support red dash. For audio and navi you need to code the unit.
How can i code the unit?
Should have gone for mk6 mfd. red are rather limited it seems.
Can code it to display audio and nav, BAP coding on or off.
...but then you'll lose the convenience menu, and live it
(annoying but once you've setup convenience, never really change them).
I have a polarfis advance plus somewhere, pf03 kessy, which I'd part with.
