Was searching for this fix and found it in the middle of an unrelated thread so said i would just post with correct title.
So my radio was not working on the key, turn on the key then you had to select the radio ON and OFF, the number 1 fuse (top left) has 2 position's . It can fit where it is running flush with the top row of fuse's or can be put in half a row down if that makes sense, it will if you have the same issue. The Radio will work with the fuse in both position's but has to be flush with the top row for it to work on the key.
