The iTrip is doing well so far (apart from being ilegal in the UK
)
I've only used one frequency and driven about 50 miles. There s a little bit of crackle in the same place when i drive through town only lasts about half a mile (come to think of it its the bit next to the fire brigades radio tower, oops)
got a longer run tonight as I go to work so will see how it goes then.
