Dear Alex
Thanks for your inquiry ,
We are trying our best to provide the best product to our customers, however, It needs some time to update the android head unit with more RAM , hope you would understand
There are 2 usb ports from this unit , for more usb ports, you can connect a usb hub
To better answer your question ,could you please send us the photo of your car's dashboard ?
Then we can help you to check it.
