You actually have a few options mate, im in the same boat as you with radio 2, Iv just bought a belkin tune fm to use with my ipod, it has a jap frequency option so you get our ipod on interference free, you could also get a frequency booster which would allow you to recieve uk broadcasts (think there about a tenner) or the option your looking at, replace the head unit. Ill eventually change the head unit but until i decide what i want this works great. hope this helps.
