Well, I was talking about hand calculations....so hands make a fist.....or I had spelling error.

Dang. I was wrong about what that meant. I can't get this to pop up on a 2018 Plat. I saw in the other forum someone did it on a 2018 502A which should be the same as mine. Just to recap: I'm getting in the truck, shutting the door, holding "OK" on the steering wheel, pressing the Start button, waiting for "Accessory Mode" to pop up, when it does I push the brake and press start, all while holding "OK". I'm just getting the regular screen. Does the productivity screen have to be on a certain screen? IE MPG screen, digital speedometer, tire pressure, etc?

Thanks for posting this!

I figured there was some way to do this. My '02 BMW had a similar way to insert a correction figure to correct the mpg reading.

Rock on!

Release the OK when the accessory screen comes up, the gauges should go into a buzzing state, then press brake and start. Ran into this earlier and could not get it to work, then for the heck of it released the OK after teh accessory screen popped and it worked.

I'm pretty tech savvy and can follow directions, but I'm having trouble getting it to work on my 2015 502A Lariat..... Any hints or tips I'm missing?

Skip the start button without starting and go right to starting the vehicle. Pops right up. Couldn't get into the menu any other way.
