New 110 Owner....

Hi,
I have just become a Land Rover owner and was advised to join Landyzone.uk as i will be bound to need help at some point!
Well this is my first time using a Forum and sure enough my first cry for help / assistance........
1st Item: I have rusty fuse terminals, can anyone advise the best way to get these clean.....
2nd Item: I have fitted an old CD/Radio and new areal, however i can only get a few radio stations any suggestions?

Thank you whoever, and sure i will be back soon.

just get a new fuse block thing and switch over, easier and no messing about cleaning it up and wondering why it won't work
