My current problem is that I have been using Motorola model 325 as a bluetooth device for my car. This device works excellently with my older Nokia phone (6700 classic) having Symbian 4.0 and I can do voice dialling very easily while driving. It also announces the name of callers for incoming calls. However this device does not work with my Sony Xperia Ray with Android Ice Cream Sandwich. I want to buy a new bluetooth device for my car. Kindly provide me the make and model numbers of devices which will work both with my Sony Xperia as well as Nokia mobile phones. PS. With the Nokia mobile phone this device reads the last 25 caller names from the phone into its memory but it is unable to do so with the android phone.
