I have been using the RNS-E as my radio for a few weeks now and I must say I am disappointed with the sound quality. Its probably less the quality of the sound and more that fact there is less control over the way the radio sounds. They symphony 1 had bass MID and treble controls while the RNS-E only has Bass and Treble. Also the symphony 1 had a hidden EQ which allowed granular control over the sound system. This EQ along with the debose option on the symphony 1 enabled the user to transform the sound system to produce harder hitting bass and mids with very clean treble. I really liked the sound of the symphony 1 and never thought it necessary to add anything to it, but with the RNS-E, I am looking at adding a possible crossover and an Amp to improve the sound. The navigation fuction and the Display of the RNS-E is phenomenal and a worthwile upgrade, I just wished the same control over the sound could be acheived.

I tried debosing via code but did not make any improvement. It maybe something is not quite right with my install, but all the speakers work, and fader and balance tansfer sound correctly so I don't think so.

I have heard the same thing about the Nav+. I think the manufacturers of the Nav units focus more on the nav peice more and less on the audio portion of the unit

I tried with Bose off, but I think I chose the A4 setting. I will try bose off with A6 and see if it makes any difference. It is possible that the RNS-E does sound better as a replacement for the symphony II. But I really think the biggest difference lies in the hidden EQ which either the RNS-E does not have or the no one has found yet.

Here is a link that discusses in detail the hidden EQ and how to access it.

Tried multiple different coding schemes such as bose on or off and A4 or A6 and basically sounded the same. I am going add a Kenwood KSC-SW1 for more bass and mids.
