I Have a parrot bluetooth kit fitted, I did not have to record voicetags the system is very clever and it converts the txt entries in your directory to voicetags.
All controls are voice activated, i.e. accept, reject, dial a number, dial phoneook entry, play music.
Really is neat piece of kit it even understands my thick northern accent.
Comes with a little removable touchscreen pad and also allows you to play MP's off your phone through it. Not tried it though cos I have Ipod.
£180 fitted, integrated to satnav with volume control.
