MFD replacement not workin just like the one before

I bought my Prius with the screen not working it always said “check the connection of the air conditioner” and the audio is off my new replacement just came in today and it didn’t work was just the same thing. I looked all over the place and still can’t find a video or nothing about it any suggestions on what the problem may be? If ik prius were this difficult I wouldn’t had gotten it

Also my mfd doesn’t show anything from the outside temp, the mile range, or if any of the arrows that show the battery is being charged

 

Hey so I had bought a new MFD for my 2005 Prius nd it still shows “check the connection of the air conditioner” and the audio still doesn’t work. I went back to check each connection and there is a white and red wire that doesn’t even have a connection to anything on the MFD or anywhere else behind it. Any suggestions on what to do the MFD I bought was tested in another Prius also and worked but in mines it just doesn’t. Need help I don’t wanna have to pay for an overpriced repair. The MFD also doesn’t show the fuel range or if the battery is being Charged or not

 

The connector that I found literally didn’t hook up to the mfd or anything behind it was just hanging behind it as we speak

 

My 2005 Prius is still sayin “check the connection of the air conditioner” with the new MFD in the audio doesn’t work only thing work on the steering wheel is the defrosters, MAX ac button, and cruise control. I swapped out fuses that were blown and still nothing is there anything else to check for will the AMPLIFIER be the problem of this situation. My 12v Battery reads over 13v and I can’t find videos ab the MFD saying “check the connection of the air conditioner” if there’s anything else I can do plz lmk im trying everything I can rn

 

The battery is in good condition

 

I bought the MFD from German audio tech it was supposedly a fixed MFD but when I plugged it into mines it didn’t work. Checked all connections they look good and nothing looks wrong wit them. But maybe it might be no signal?

 

My old unit was doing the same thing the audio wouldn’t come on at all and the mfd when I press climate it says “check the connection of the air conditioner” I got the mfd from germanaudiotech

 

Everything on the MFD is connected when it still shows nconn on to anything with the mfd I’m trying to get it working since it’s hot in the valley and I burn gas in my other car

 

Audio H/U Ncon
G/W Ncon
DSP-Amp Ncon

 

It’s a red and white wire and I’ll take pics when I get back home. My new MFD model number is 86110-47081

 

It has the map button on the steering wheel no backup camera
