Hi together, my daughter has her first car on the 18th and of course there is a theme that the dad is supposed to solve. It is a K12, 25 edition that can pair an old iPod in the center console. This interface to the radio can also control my old iPhone 4s and play music – including the steering wheel button control. However, the daughter has a current iPhone with USB C port. The radio can bluetooth but only the telephony works over it. I have an adapter from the connection a uf Lightning tries, from there only the charging goes, the control already does not work any more, so that I derive that an adapter on USB C also brings nothing more. Then I looked at the coupling more closely and found an adapter Dension degwn-8570-92 (see picture). It has 2 inputs – once the thicker round and as I mean a 3.5 mm jack input. I thought via bluetooth receiver over the jack input I could pair the iPhone but already try over the jack now my question – has for the problem – current iPhone and existing radio of one a solution? Alternatively – is there a more current radio, which I can install and the functions like steering wheel buttons, hands-free, etc. continue to work? Thought of a VW radio, which looks similar 😉 Other topic to the car – wanted to install new H4 pears. On the driver’s side this was still with scratched hands, on the passenger’s side If I wanted to solve the headlight, I didn’t get it. Then I made out on the right side of the frame (with such a gray socket screw), thought about it you can dismantle the part. But was nothing – is that possibly the headlight height adjustment on which I turned around and how can you change the stupid bulb?
