Hello!

I´ve bought a 1995 Riviera here in Germany and the display shows all values in Miles (and temperature in °F).
The manual doesn´t tell me how I can switch it to "Canadian" mode with Km and °C.
The LED display is prepared for this.

Can only a GM Dealer do this via the diagnosis interface?

Who can help me?

Is there no quick & dirty solution the Riviera pro´s can provide???

I always wondered that myself... I've had the whole gage panel out and I never saw anything on how to change it, no jumper pins or whatnot... I would guess a tech-tool might be able to command the PCM to change it somehow... that's just a wild guess... I've had nearly everything apart in my car, and I never saw anything about how to switch it... I'd read up on this.
