My original version is this small screen,and i had no navigation. What i got was 10 inch version,and naturally this part where hidden compartment goes needs to be removed and plastic around it cut to fit.Should you decide to revert you can buy used trim part for less then 50e.That is only if you have one like mine,without big screen.With big screen,nothing needs to be cut.Here is a bunch of cables if you want do it yourself
What are the some of the featured you lose?
Honestly none,as far as am aware of.Most important thing is to have right can bus decoder for that particular model of car/multimedia.All the steering wheel buttons work for controling multimedia.Hydraulic system visual raise/lowering are displayed on center console right next to where speedometer is anyways.
You wont be able to use old radio but that goes without saying
Information regarding fuel consumption is properly displayed and you can view it on multimedia screen(just forgot where exactly) but i saw it works.Visial when ac is turned on for some reason not displaying proper numbers on android screen,but can still see it on small screen right above ac screen.
Parking sensors work fine and there is visual showing which one is closest like green,yellow red color.Thing about it tho is that it picks up little closer to obstacle then what the case was with oem,but it still works fine.You can also instal camera but i didnt do it(and it takes like 2 hours to route all the cables and connect everything properly)but it's possible should you chose to do so.
Bluetooth for audio and calls work but quality is honestly crap.
Radio works and quality is fine,but dont expect as many stations as you had with rd4,ng4 etc.
Sound quality is better then original radio(mine was rd45)maybe beacouse this version has dsp chip,idk but it's better.
Every android application you would expect work.Right now am playing music via usb stick,but you can also copy that that to internal memory of device.Turn on time is really fast,one key turn and device is on,like 3 sec. Hard to see quality when picture is taken by phone but it's chrisp and bright. Price was 390euro+20e for instal.
This one was a bit more expencive since it is intended for eu market(Germany) and you can see that on box code.
Memory 4gb +64gb of rom
Manufacturer is Junsun
Overall am satisfied,google maps work super fast and you can share internet via hot spot on mobile so you are always updated in real time.You can use offline maps just fine.Maybe i missed something,and if anyone has any questions feel free to ask.
This might be updated with some audio speakers upgrade if i decide to do that
