Hi i am new to this forum and to the world of Skoda I have an octavia vrs wagin mk3.5 and I have a couple of issues regarding the infotainment system. 1. My android auto is temperamental. It fails to connect 95% of the time. Phone is a Samsung, fully updated. Is it likely to be a cable issue? Am I better to buy a dongle to make it wireless? 2. I don't think that this is the most up to date software. What are my options for updating? I am still waiting for the dealer to supply the sd card for navigation. Thanks in advance Mike
