Hi fellow Audi fans! I've followed this forum for many years now, but this is my first post. I excitedly picked up my A4 Alload last Tuesday. It's a mid 2017 model. It has the MMI Plus system with audi phone box. First thing I thought I'd do is connect it up to my phone and see what this thing has to offer. As I don't want to use Audi's extortionately priced SIM, I thought I'd use my own internet connection. There are two options; 1. Buy a SIM (ie a second SIM from my current provider) 2. Use rSAP. As I have a Samsung Galaxy S8, which has rSAP, and to save money, I chose the latter. Being male, and IT professional to boot, I ditched the user manual and set up the connections myself. Everything worked fine - well almost everything. I've got internet connection, I can listen to online music via webradio, I can stream music via bluetooth, I have access to all my contacts, etc. You might think, good for you! You might also think, shut the f@#k up and tell us your problem!! Here goes; Internet connection is available (via rSAP). When I connect my phone via USB I am also able to start Android Auto app. When I go to navigate on Android Auto it says "internet connection is weak" or "internet is not available" or words to that effect. Before connecting USB, I have the connection bars and the internet speed (lte, etc.) on the bottom left of my MMI screen. When I connect the USB cable, those symbols remain, but an additional phone symbol appears along with a second connection bar. I love troubleshooting. But, at the moment, I have no answer to this problem. I even read parts of the user manual - that's how desperate I was!! I've done a lot of online research, but have not found a solution to this problem. I've even searched german forums hoping I'd find something there - 'tis my second language my friends! . I found nothing, leider! Has anyone here had the same issue? Could you find a solution or did you use a workaround? It must be possible because loads of people use Android Auto with their Audi once the Audi connect grace period is up. Would be great to hear suggestions from someone. It would be even better if I could resolve this issue! Audi really should provide more infos on how to use their products. I mean come on, they charge us enough for their cars and services. Thx all.
