ooo interesting. So I noticed on this little box there is a 3.5mm jack. Is this what your talking about? you plug your ipod into that 3.5mm jack in the box I found and run the wire into the glove box?

How much is one of this boxes worth like? £40?
 
Yeah run it to the glovebox, tune it to your radio and should be fine.
Check out ebay for what you'd get but you could use this yourself :)
