hello I have a renault megane 52 plate with a gamme radiosat, my problem is that although i have a code for my radio it isn't accepting it whatever method i use i have tried the satellite wheel and the key board but just get the invalid beep, if anyone has any suggestions i would be very grateful. i bought the car second hand and i am using the code that was in the leather renault wallet. I apologise if this post is in the wrong place i am a total newbie. thank you
