Motorola V710

Ive been checking and checking the rewievs and forums of the Vzn phones, trying to make up my mind, I really need a new phone and in despite of the bad reviews I I like the V710 for many reasons I have just one question, It would b very nice is somebody could help m in that way Ill get this one instead of the new Vcast Audiovox.
How good is the mp3 player in this phone, I just need the Trans flash card?, is STEREO?, could I plug an FM Transmitter and use it in my car??
Thanks
