Yupp, these radios are build in fully automated assembly and soldering machines.
This and the combination of road vibration leads to cracked soldering connections because of solder being way to thin.
What can you do now?
If you have the tools get the radio out and open it.
You need the connection from the main board to the display. Mostly two printed card boards are used and connected via wire bridges. Some have flexible plastic wires(be extremly careful with those- they break very easy).
Watch at the solder connection. You will see a very thin break at one or several solder connections. This is the cause of the flickeing display. Add a bit solder and your done. Test it before reassembly!.
It can be possible that your display has conductive plastic as a connector. So no soldering is needed. Dirt (dust)is failure no. 1 here. I
t can be cleaned with a special cleaner. no alcohol, no degreaser! But very difficult for the noob- it's an electronics tech job.
The other cause (which is very rare!)can be a faulty high frequency display unit. These displays are operated by a HF unit. There is no repair, only replacement- so it might be better to replace the radio if so.
A pic of the radio would be nice...

I do not encourage you to open this unit by youself neither to try to repair it by youself if you don't have the skills.
A flickering monitor is definetely an internal power supply problem. No biggie at all.
But do not touch it if you never done it before. Go to a car hifi shop they might be able to fix it for you.
The risk of destroying internal SMD parts is way to high.
Sorry, but I can't tell you something better than this.
If you wan't to save a bit you can get it out of the console by yourself- just make sure you have the code before disconnecting it.
