the ethernet port is viable. i'm not sure how to access it while the vehicle is in use however. i'm sure somene on here can shed light on viability of that, as well as Wi-Fi. there may or may nto be issues of interference on the Wi-Fi element but i can always mount the empeg at a location other then in-dash if that's an issue.

speaking of which, since i haven't stated it already the car this will be going in is a Mazda RX-8.
