Thanks guys
@leshkin - not sure if the Connects2 CTSAD006.2 has all the bits I need. Are you saying I would need both kits? Going to take the plunge tonight and install next week.
@shadow - thanks for advice, although I'm an Apple fanboy, and will always have an iphone, or at least for the foreseeable, as does my missus (who spends quite a bit of time in the car) and most mates, so not too fussed about the android connectivity. As for the volume, with the above kit I hope to maintain the steering wheel controls, so will be able to turn the volume down using that? Did you not set that up? As for the DAB and Sat Nav, yeah that's my biggest regret, although hopefully the apple maps will do part of the job, and with the CarPlay I'll get to use my spotify app, as opposed to just downloaded songs in my iTunes.
The pioneer system seems to have everything I need, predominantly CarPlay, bluetooth and the ability to utilise spotify, maps etc. I was looking at the new Alpine HU with CarPlay, more expensive and no bluetooth.
Will hopefully post succesful pics in a couple of weeks.
