It should easily be able to handle it with modern Bluetooth stacks. But they should also add multiple channels of Bluetooth connectivity. And they need to have a mixer for audio on the display. Where are you can play music from your usb, navigation audio from phone, and messages and calls from two phones. Individual audio balance would be nice but using the mic to optimize all sources would be better. Also need audio output of the mix via Bluetooth, when vehicle is in park, to outside speakers for camp mode
No, it shouldn't. Show me a BT stack that is capable of basically pushing a mirrored screen over any of it's protocols, and I'll gladly eat my words. I'll literally print out this response, and eat it.
This will change in the future, perhaps, but the correct "stack" you're looking for is a Wi-Fi one.
