2018 T680 w/o NAV. What radio can I use with wheel buttons? can I upgrade the buttons or modify them somehow with a different wheel to be compatible with other radios?

2018 is likely to be the newer version of NAV which some called it smart nav plus. The connector would be the BT ISO DIN. To connect to the steering wheel controls read this page, https://www.bigrigstereo.com/STEERING-WHEEL-CONTROLS.html.
