Tee into the MOST , all original functions work and more.
I am currently using a Bluetooth and DAB add-on unit by Pioneer that plugs into the Auxilary input, but it's only good in the cap cities, Mandurah and the Gold Coast, once outside of those places, you're limited to FM or MP3s or if you have a phone signal, music streaming via Bluetooth. I do a lot of country travel, and still need AM, but the C30's module is stuffed, which is common, and the CD player is also munted too. I really would like to add a reversing camera too, without the mess of an external screen or dodgy rear view mirror replacement.
