What is this remote control for?

Hi, I am hoping that somebody can help me identify this remote control and what it might be used for. TIA Andy

It chooses different functions on the reversing camera screen, I think someone posted instructions previously so try using search facility above for reversing camera

If you were given full paperwork including all the individual instruction books look for  reversing camera

Its the remote control for your ECHOMASTER  MM-70-CL 7" clip-on mirror monitor - which links to your reversing camera:

Thank you both; needless to say this was missed on the handover and there is no instruction booklet. Now i know what it is i can look up how to use it . Thanks again!
