It's time to get the audio for this car back to factory spec
The original audio isn't the best on the planet but it's pretty good! And it's better than the mess I had before sorting things out.
Special thanks to Tom Mitchell at Becker Auto Sound in New Jersey for helping me with the purchase. The new BE1692 head unit with Bluetooth, the Bose amp, and the Hirschmann antenna are all covered with a 3 year warranty. For more information on the stock MercedesBenz radios check out:
