Super cheap, cheapest of cheap head units

custardy

Not £30-40 but I fitted a 2nd hand double din android head unit to my car.
relatively easy fit. loads of features.
some software oddities. keep in mind these as seen as Android phone/tablets so will throw up some issues with software.
Eg I cant cast to my radio,cant get Netflix
Mine works over canbus so steering remotes work,temp sensors etc.
I can watch Youtube etc. Reversing camera,check fault codes with an OBD adapter 
One annoying feature is I can black out the screen by touching a symbol top of the screen. Its stays dark using the steering controls except the volume controls.
Where the screen lights up.

ISO is the standard (those 2 plugs I referred to) so it's about adapting the car to those plugs, then any aftermarket unit should connect to those. My Chinese one came with 2 different ISO connectors (for Japanese or Korean cars I think?) and also just bare wires. They're all labelled, and I just connected these to an ISO plug I had. There are always other cables though.

An important basic one is though, that there are 2 power cables. One provides power al the time, one when the 'ACC' is on - red and yellow they should be. You need to either connect red to red, yellow to yellow, or red to yellow. Test this before putting everything back together. If you turn the car off, and the unit stays on, you need to swap the cables.

And enjoy this before your next car probably has CANBUS and things get a bit more complicated!
