![]() It mostly works great, but it skips and cuts out relatively often. I have one of these going from the back of the unit and mounted to the console. How's your setup work? Is the MA1 plugged directly into the head unit? Immediate power-off upon turning off the car Faster power-on times (the integrated usb would power on the MA1 after several seconds) As the cigar charger gets power cut off immediately upon turning off the car. In this way I will still have one "fast charge-usbc to usbc" connector available in my cigar charger, so that I will be able to recharge my phone fast, but the cool thing is that now the MA1 turns on and off IMMEDIATELY with the car. I then proceeded by connecting the power cable to the "cigar charger adapter" which turns on and off automatically with the car, the data cable to the integrated USB, and I connected my MA1 to the female connector (Data+Power): Knowing that, a little bit of soldering later: This differs from the usual usb-Y cable as it usually "merges" the two power inputs, but that would leave our device on again. The female connector will receive power from connector 1 and data from connector 2. The male connector 2 will have only the data (D-, D+) cables connected and the power contacts will be left disconnected. The male connector 1 will have only the power (VCC, GND) cables connected, the data contacts will be left disconnected. Make one cable, with two male connectors and one female connector. Reading the docs around I noticed that the USB standard does not check for load on the Power contacts, but just "offers it" as devices might require external power to work. This is relevant because USB3.0 uses waay more contacts.In USB2.0 we just need: Here it's the pinout for the USB connector: The good(/funny?) solutionĬabled Android auto by standard uses the USB2.0 standard. Disconnect Android Auto before turning off the car. To make it work again EVERY TIME I would have to either: clear data on the "android auto" app, remove the device from "known android auto" devices or. My phone receives the message and just ignores that wireless android auto. The MA1 still gets power from the car media center, but the media center is shutting down, and it's telling the MA1 that basically. I turn off my car, but I notice something strange. I now can connect my phone to the fast charge connector and I am happy. I connect it to the car via the integrated USB and everything just works. Connecting Android Auto to my car via USB was painless and so smooth.But the slow USB2.0 charge speeds were a big "no no" for me.Īlso, we are in 2022 so we need wireless.
