Grand scenic no memory radio trip and clock

I changed the radio in my 2005 grand scenic and since then every time I go out in the car the radio has reset so has the trip computer and clock resets to 0.00 and flashes. I have checked fuse in glove box and it's fine also checked fuses under bonnet and all looked fine although I haven't a clue what I was looking at. Someone told me there's a common fault with Renault dashboards and they need the clocks resetting? I can't help but think it's not this problem as everything else works perfectly is there any other fuses I've missed out?
