Possession of this part since October 2011 - Installation has made my workshop in conjunction with the new car delivery. Device worked properly at the beginning - it was coupled with an iPhone 4 - absolutely no problems! After about 4 weeks, I noticed that the remote control reacts very slowly - at first thought it is up to the battery and have it replaced at once - but the problem did not get better - rather worse! The intensive browsing the Parrots forum then brought me the solution! It is a simple contact failure in the remote control - the contacts are just not close or not strong enough out on the battery, so that there is contact problems. The solution was very simple: just press with a very thin screwdriver contact slightly forward and already works part as it should! Since this operation I had no some more outs! I hope you could all those who help the same problem.
