Hello guys, because I don’t like the “big” free-receiver from Volvo (keyboard in dashboard; 2nd SIM car; handset in the center console) etc. also wg. of the sound not so great, my dealer recommended the BLUETOOTH solution (cost approx.450 €). Does anyone have the thing in the V70 ? Experience with sound and operation ? Where is the Micro ? Radio mute circuit ? … … Are there descriptions about functions, operation and supported devices ( Have a Siemens S75-mobile) Thanks for hints !!!
