Koason 1920HD 12.3inch Android Screen Monitor Display Upgrade Multimedia Player GPS Navigation for BMW 5Series M5 2010-2011 F10/F11 CIC

I hope my review will help others.The product is overally a good one but considering the amount of money paid I would expect:- Official installation video and install documentationThe videos on youtube are done by regular folks and don't apply to all models- There should be a mentioning that the adaptor connecting to the original loom and CIC unit doesnt fit as as expected, therefore requires a bit of extra pressure applied- There needs to be a mentioning that you need to open the centre console and draw an AUX cable...This is how the audio for this unit works. A bit silly to be fair but it is what it is.The sound output is actually connected to the aux of your CIC unit.- The WIFI of the unit is flaky and sometime it drops for no apparent reason.I've had it connected to both my home wifi and to the phone hotspot while sat at the drivers seat and only get 2 bars of wifi signal.5GHz or 2.4GHz don't make a difference.- The Android Auto feature is yet not working for me.- The screen bracket/holder isnt as stable as you'd wish for the price paid.The screen is shaking while driving and due the screen being quite reflective its an unpleasant experience.- The light sensor of the screen is definately not the best one could hope for.Sometimes the screen is too bright/dark.Overally a good product but if I knew all of the above I would think twice before buying.Thanks
