I'll give an example of my unit on my Ford. sample code 1234
code shows on switch on with four lines flashing. then static. line one flashes... press station key 1 once in goes 1
Line 2 flashes.... Press station key 2 twice in goes 2
Line 3 flashes.....Press station key 3 three times in goes 3
Line 4 flashes.....Press station key 4 four times in goes 4
what I wasn't doing was setting it to memory by pressing key5
You MAY be doing the same.
Or ask the Dealership or audio shop how you enter the code.
If they do and it works ok if it doesn't then it's probably 'locked' read on.
You may have accidently 'Locked' the system pressing in the code so many times without setting and it's automatically locked which means you have to take it to an auto audio shop or a Renault dealership to have it re-coded...this is not free. and you need the registration document with you and check with them what other ID is required.
