I decided to replace my Sat Nav touch screen head unit with a more modern Android Auto unit. My car is a 2013 MX5 Sport Graphite. I managed to strip everything out OK having followed a couple of vids on-line. I thought it would be a case of a simple iso harness connection however the existing Mazda connection is a much smaller white 20 pin affair.
Has anyone changed out their sat nav head unit and where can I get an adaptor to suit? I have attached a couple of photos. Hope you can help. Thanks Andy
Yeah, I have ordered one of those that allows the steering controls to work. Again unfortunately the final power connection is a larger size than that hard wired in the car?
Hi, yes that is the one I purchased. Unfortunately the large red block is too big and does not connect with the white smaller block in my photo? Any other car I worked on, these are quite straight forward. It appears that the Panasonic Unit NVA-SD8110 has a different connection? Odd. Hopefully someone with a Sport Graphite or 2013/14 car has come across this. Thanks for your help MickAP
Sorry I couldnât be of help here I had a look around and all the leads I found were Bose/non Bose standard units. Nothing listed for yours (as Iâm sure you knew anyway) good luck and maybe someone has done this, will look in here and post a solution

Thanks Barrie. Appreciate you looking into this. I guess an auto electrician might just cut the connectors and splice the wires together? Once fitted it will be staying anyway. Cheers
That would have been my next suggestion to have something made up? Roadster Robbie has pretty much hit the nail on the head though, a Mazda âadapterâ from the main loom makes sense

Okay, no point in creating a new thread.
Mine is a 2013 Sport Tech.
I have all mine out and disconnected the original Sanyo harness EXCEPT for a single GREEN and BROWN wire which is attached to the harness.
I can see that the BROWN goes to the handbrake switch, so can splice that one in with the new loom.
Now the GREEN one.
It goes around the back of the Glove box and down towards the fuse box and thenâŚ
So guys any idea what this one is for??
I think that it âmightâ be for the reverse light link system?
Now I know a few have replaced the NVA-SD8110, so any help would be greatly appreciated.
(Great fun getting that 10mm bolt out!).
