Hi, would love some advice, my 2018 CMax was working perfectly when I bought it five months ago, but slowly functionality seems to have gone. First the Apple play connection would not work, I could plug my phone in and see the apps on my screen, now that’s gone. Then the GPS signal kept dropping, and now I can’t access the satnav at all, it’s just saying navigation error and an error tone each time I try and open navigation. Any suggestions?! Have tried system reset. And it won’t connect to my phone to download a system update.. help!
