On 98-00 LS cars with Nav.......what do the steering wheel mounted controls do?
Do they control the radio/nav in any way, and if so, what features can this control?
Does anyone have a shematic or wiring diagram showing wire color and purpose?

Thanks for you replies.

The steering wheel controls have nothing to do with the NAV system.

The buttons on the right side of the steering wheel control the functions of the trip computer on car with and without NAV.

 

ratts ! Oh well .......thanks for the reply.

 

Also they are used to show if there are any malfunctions.
