What button on a car radio...?

Question

When i put my radio in my car on certain station, it seems to stick on it for a few seconds and then automatically changes to another station... The 2 stations are linked, one is National and then the other one is the local station. It happens both ways too ie if i listen to the local it will also jump to the local every now and then too..

I dont know if anyone knows the 2 stations Capital FM and Southern FM in the UK??

Its a new car and im sure it will just be one setting, or a button that ive pressed, like RDS or something..

Flipping annoying though!!

Many thanks in advance.

Probably engaged the PTY button and its changing stations to suit.
