Hi Everyone,
I did these steps with my V3m and my late production Z1, without sucess:
Performed a level 3 reset
With the AVIC off, called another phone and lowered the handset volume to zero.
With the bluetooth earpiece called another phone and lowered the volume to minimum.
Powered up the AVIC, connected the V3m.
Called the house phone and the echo was present.
Downloaded the upgrade from Ducatiboy and using Nero created a data cd on a SONY cd -r. Upgrade installed flawlessly.
If, after all this, I keep the caller volume on the AVIC lower than 2 bars there is insignificant echo. D
