I have an igroove, just over 2 years old. Worked perfectly well with my ipod and initially with my new iphone 4s but it's suddenly stopped worked with both. It's not the power as the green light comes on and it makes the "docking" sound when you put the ipod and iphone in, it's just no sound comes out. Anyone able to help or should I just accept that it's broken and invest in a new docking station? Thanks.
