anyone using a Dynavin N6 on E90?

just seen this unit and it looks very good for a replacement to the professional radio.



I'm wondering if anyone has installed it and can comment on how well it works with the car, in particular:



button lighting matching original interior lighting scheme?

any lag between using steering wheel controls with the unit?

any software bugs, annoyances?

does it connect to the armrest usb/aux in sockets? (I can probably make the USB work as its a case of just connecting it up behind the radio, but what about the AUX input socket?)

is the nav any good? what software is it? do you have to pay for map updates, etc...?

DIY install simple enough? I don't want to hack the car to pieces, I may put the original HU in if I come to sell the car or if I update the car software.

thats all I can think of for now. any feedback would be welcome before I go out and buy one.



also, the professional radio is the base stereo system, no amp, but does have the MOST loop which connects to this unit and music doesn't play without it connected.
