I didn’t get a picture but it was more or less the model pictured here. The radio was showing a bunch of stuff they didn’t want to see, turns out it was stuck on “demo mode” and listing a bunch of features. The interface was unintuitive but luckily he kept a manual, so I navigated through the settings menu and turned off the demo. Sorted.
There are people driving who are younger than the last generation of cars where aftermarket radios were commonly installed
