The M303 is a nice looking piece. Unfortnately for me, I wanted to keep the factory look of the dash console, did not want to spend that much on a headunit and I do not like to talk on the phone while driving anyway.

Although the M303 utilizes Parrot Bluetooth, audio data bandwidth is still compressed using its A2DP technology for stereo sound, has a 30ft receiving range and boasts an output of only 2 volts to the amp.

When compared to the price of a brand new headunit, I really like the performance aspect of my BT modification. Audio data bandwidth is un-compressed using 4.0 Bluetooth compliant with AptX codecs for Hi-Def sound. With the line driver, output voltage matches and even supercedes the 5 volts input spec of our factory amp and I can play my music from 100ft away when camping on a weekend or at the beach.....all for a fraction of a price of a new headunit.
