Been simultaneously working on the backup camera mod from another post in the mod section, while stumbling upon this...
https://sourceforge.net/p/mylink-unlock ... wiki/Home/
Took a gamble after I saw a Spark EV 2014 owner tried the 24.5 firmware with moderate success, only mine's the 2016 model... Do not do it on a 2016 folks
. It worked, I have MirrorLink in the app screen now, but not only does that not illuminate when my S7 is connected, Android Auto enabled with the USB cable plugged in, etc, but the MyLink screen in general is extremely sluggish now, responds to touches 2 out of every 10 seconds, steering wheel buttons broken even after the fix applied... AND, the icing on the cake, the MyLink screen doesn't turn off when the 2nd blue wire on the aux connector is cut, effectively making the pavados method worthless on this firmware. I contacted my dealer after failing to find the 16.4 firmware online anywhere (had previously looked before taking the gamble knowing I probably wouldn't be able to downgrade myself) and am going to have to shell out $140 to have them flash the stock firmware for me again. I asked and they will not provide it to me on a flash for those here which I had been hoping for.
