I got an Android Screen Car Navigation Head unit from China...

[Helipedia]

The seller at navicar provided a software update for the head unit and information how to change the wiring of their new switch. Here's a link to the info I have and videos of the process.
Following this made the supplied hazard switch work the hazard lights. I did not get the switch itself to flash though.

I just updated the head unit with the .bin-file and the hazard works now without modifying the wires... I am happy now! Take care that the USB stick isn´t too large - will not work!

Now I can move on to the next problem, the lighting of the buttons and switches! Does anyone have instructions for me?

I can see a few people have installed the Acardash unit for the 4200. I've ordered one of these. Just wondering if there have been any quality problems since the previous posts. Also, the supplier only offers the screen frame in black or carbon fibre. Does anyone know where to get the factory colour codes for the centre console trim in order to colour match, or is it trial and error?

I'm also interested in how people are doing with this. My questions:
- The sound from my current, as built system is awful (thin & unlistenable) even though I've had all the speakers replaced with Focal units. Am thinking it may be the NIT (?). Does this Acardash SOUND good?
- The reversing camera option looks good. If I use the wireless option, can it be fitted without damaging the bodywork. Can it be removed to get back to the original as built car if needed in the future? (Assume rest of the system/screen can be removed/reinstated.
- I have a Spyder - any reason why this would be more difficult etc to fit on a Spyder?
- I'd like the DAB option. Is this an easy add on?
- Is the screen/system quick & responsive?

Any thoughts on these gratefully received!
