Recommended on here!! - very impressed so far / the Pioneer App, which I was worried about and only has 2 stars on the App Store, appears to be excellent - so far. Using the phone as the processing horsepower means all the functionality is instant. Sound quality is solid (with focals all round) - multiple pre-set equaliser with 2 fully custom options. Nav you can select your preference and then this is integrated in the app (I use Waze). I mounted the microphone on the steering column (recommended on here!). Even though a DAB system does not come with a DAB Aerial - bought an Ebay special - round disk and mounted lower offside windscreen - works fine but possibly better options - will see how I get on. Integrated phone holder is solid and sturdy and rotates so you can have phone landscape/portrait as required. Functions either via bluetooth or you can plug in - charges phone on the go.
Only issue is that the stereo recess is a little too deep to ensure a fully vertical angle with the phone in the holder - so does need 10-15mm spacer to ensure correct angle on phone - or you can just live with it!
So far so good!!!!
