Hands free?, which do you recommend me?

Salu2, Foros/as, I need to help me with this undecision, I am looking for a hands -free kit to be possible Bluetooht, for several vehicles and several telephones, and of course I look for something with the three B, well, beautiful and cheap, you know some model that fits this and where to find it.
Thanks for your knowledge and help.

May I know you have two quite good options, (the cheap ... depends on how you look).

1º Put a parot in the car, it comes out percentage more or less, you have to disassemble the radio and in the ISO connectors interspersed the parrot switchboard to do the \ "mute \" function when the phone sounds and the audio goes out through the speakers.

2º Take advantage and change the radio for one that has Bluetooth, (Vieta VP45C), at the Mediamark it came out for 109 euros, remove the old woman, you put the new and resolved case, it also has a lot of stories, USB port, SD memory card ... The truth is that I cannot complain.

All the best.

Thanks again, you are a real crack.
Very adequate and interesting your answers in this and other topics. You are true help and an excellent partner.
Thanks and greetings.
