I have got a unit of AVH-Z5190BT yesterday and unfortunately, the dealer or the installer are well educated enough to complete the installation process and I had to spend a lot of time with them. I was totally misguided and was never informed that my phone should always be plugged into the system while I am navigating with google maps.
Is it not possibe for the system to complete the navigation process without hooking the phone. I have got a Google Pixel XL phone with the latest android OS. Your detailed help will be much helpful.
