I was user of D2 (that still works!), That I enjoyed, despite a rather special architecture, but I was used to it. Even convoluted configuration thereof, but yet + complex. But this poses a real problem is the touchscreen that responds uncontrollably: no response, or access error very often. The display covers, I thought resolved, has not changed: the vast majority of them do not appear (music purchases Oldest) The random playback mode is still listed or + complicated to learn than the D2. Only consolations: the sound and the look, which is not quite nothing. I generally do not recommend this choice I regret.
