Can anyone tell me if there is an update for my NTG5.1 as I'm trying to get android auto on it. I have used a Summor NTG5S1 for Apple/Android OBD2 Auto Activation Tool NTG5 S1 CarPlay Protocol Communication for Mercedes-Benz. I now have the icons for Android and Apple car play but they do nothing. I've been reading there may be a possible update for the NTG? I've ask Mercedes and they want to plug it in for £175 just to tell me if there's an update or not.
