Steering Wheel Controls - Ipod Sound problems

Anyone had a problem with the steering wheel contols when selecting the next ipod track. Seems to work fine when first plugged in and the first track plays, but although the track descriptiion appears on the dashboard there is no sound when using the up and down arrows. Works if the tracks are left to run on, just no sound when the steering wheel controls are used. No problems with the radio and CD player????

Needs a software update for Blue & Me,

I had same problem a couple of weeks ago, dealer sorted it.
