LNO oipny SWUO LP OIN OL Ly NMOG QNO JIN OIN Using a Bluetooth HandsFree car kit Adapter with Android Phones running AndFlmsg The price ranges from 15 to around 250 for the top of range units Low cost units seem to work well By removing the internal speaker I was able to fit all the signal level adaptation and the VOX inside the unit rather than have a separate box but that is a personal choice as keeping the loud speaker can provide extra feedback These units typically clips on the sun visor of the car and have a built in rechargeable battery giving around 10 hours of run time are small approx in cm 10 x 5 x 1 7 or in inches 4 x 2 x 0 7 and light weight around 100g originally The minimal device specifications are that it handles either the hands free or the headset Bluetooth profile The A2DP profile is of no use in that case as it is for one way high resolution stereo audio The thicker the unit the easier it will be to fit the electronics inside The model I used is an Advantalk Nova but I am sure a lot of other units would fit the bill The key criterion is that these units pair with your phone or tablet and can be used in a phone call as interface for audio in and out Required adaptation I basically left all the electronics of the units as is which is a plus as it is all small surface mount components Only the integrated speaker and microphone were removed The two functions required to be added a
