Isit just my headunit or a clio thing ?

Right this has been bugging me so much since ive bought the car. When i put my car into reverse and then back into 1st the headunit turns the music off and puts it to the bluetooth phone screen. Ive looked though all the settings and can't seem to find anything and ive looked through the book too.

Isit just my head unit or is it a clio thing ?
Can anyone clear up what it could be ?
 
Sounds almost like the reverse signal is being put into the head unit somewhere it shouldnt. Someone might have bodged the install if it's aftermarket.

Thats what i thought ! Surely cant be bodged its not hard to put a headunit in. They would of only had to of got a new ISO lead. Im just rattling my brains as to what it could br as its doing my head in !
My mate has the same headunit in his fiesta and his doesn't do it
 
Its been doing it since i had it so when i took the dash surround out to spray it i had a quick look and everything looked fine. Ill have another look tomorrow as ive got early finish from work.
