Cannot adjust Nav 1 to 108.4 MHz

I want to fly out of Agua Dulce toward the Lake Hughes VOR (LHS, 108.4 MHz).

But I cannot adjust to 108.4 - it goes from 108.0 to 108.5 using the small knob with the mouse wheel. I have tried with the C172 and the DR400.

How can I set the NAV 1 radio in 0.1 MHz increments?

How, what, why? I can set the NAV frequencies in both aircraft to 108.40 without any issue?!
Do you maybe have the mouse over the coarse selector? That should step 108.5 to 109.5 (+1.0 MHz)... The small increments are doing .05 MHz?! So what is the matter? Have you mistakenly tried setting 108.04? because that wouldn't work

As you speak about the dr-400 could someone pls point me to a guide or tell me how to use the third thingy? The one below the nav frequency. Sorry for being a total noob but i never figured out how to use this

That is a transponder. With the knob on the right you can set individual digits of the squawk code. Just rotate the knob to get the first digit to blink, then rotate the knob.
The second line of the display shows the current flight level as send out to the controllers.
The VFR button resets the code to 1200 in USA and 7000 in Switzerland
On the left the rotary switch is used to turn the device off.
