Screen problems with update to Sync 3.4

Hello.

  1. Check the FAQs here → SYNC 3 - CyanLabs
  2. This is expected, if you want to get rid of that message you need to upgrade your USB HUB. More details here → https://community.cyanlabs.net/docs?ascending=false&category=26&topic=4683
    What you currently have will work with media and Android Auto, but not car play and will produce that “error” message since the hardware is old.
  3. You are not giving any information about the unit, but I assume you should read this → Tutorial: Sync 3.4 NON-NAV APIM: Failure to Update to Newer Version Sync 3.4
