I am getting better learning about and configuring my dudu7 PiP properly. I just learned when you change default app it needs a reboot to take place. It would have been a much better user experience if written documentation for the dudu7 was available. This relates to all functions, features, and how to configure modules like PiP. An FAQ that properly outlines how to update OS, including all the little gotchas. The hardware means nothing if the user experience is challenging right out the gate.
Still have problem where navRadio and navigation sounds do not work together. Navigation voice is working good with spotify and waze but I wasn't a regular spotify user so its unfortunate.
