Andream Android 10 headunit is installed, factory cic with factory display deleted but lost the satilytte option supplied the splitter but installer did not use it . do i have to have a sim card installed for better playback options this has been confusing as no one knows how to program or load this headunit, i can sit by wifi and do stuff but beyond the default stuff im a little lost firmware update? Austin area has 1 place that put in unit but they do avin, wish it worked better and did more guess a large usb storage unit would allow more movies and things, sim card will add 50 bucks a month to bill and its only 4 g not 5 g. Att is my phone carrier. this item seems to needs some updates from a savy installer to optimize applications with more current software. i have a samsung S22ultra and can do mirroring seems i am not to sharp as to options with this hardware setup.
