Its a 2012, which puts it right smack bang in the range of engines that ate cam lobes and had issues with head hardness. You are correct, we are yet to leak down test it and we havent gone down this route yet because the issue appears to be electrical. Reasons being there have been periods of...

I also went the chinese android route. For what its worth, a proper Alpine unit will obviously out perform this thing in every way but at 4x the cost plus all the fitting kits, you can understand why i had to swallow my pride and go this way. The key to getting them to function non-laggy is to...
