Car insurance might cancel

I recently joined hasting direct insurance. They are now asking for pictures of the car in every angle including the inside, engine and dashboard I didn’t inform them that I have installed a kenwood screen into my car. Can anyone tell me if this is a problem?

I have a Vauxhall Astra 2013 with a kenwood CarPlay screen installed

UPDATE: Thank you guys for all the amazing advice! Turns out Hastings is shite and a waste of time so I’ll be cancelling in the morning! <3
