Dynavin N6 Firmware update! If you have the DSP audio system you MUST READ!!!
Dynavin has the 1.1.1 firmware update up on their website.....for those of you
without the DSP audio system this will offer a lot of nice little improvements over the current 1.0.1. Follow the instructions on their site to update (the link is on the bottom of each product page).
Nothing huge but some of the obvious changes:
-Changes to tuner software to better work with certain diversity antennas (like on BMWs), the "hi cut" option in the radio menu should be unchecked for us BMW guys.
-Changes to the way the volume works in nav.....when the nav voice is talking you can turn the volume knob to adjust the nav sound volume independent of the media volume.
-Microphone Gain in the bluetooth menu to allow for adjustment to each individual installation plus options to better handle multiple phones.
-Lots of small stability and performance improvements, as well as a number of vehicle specific changes for wider compatibility.
Keep in mind, this is not your PC, this update is not mandatory.....your various settings will be reset (on the radio, not nav) so make note of them before updating.
NOW FOR THOSE OF YOU WITH DSP.....
The new Dynos 1.1.1 firmware offers many improvements in the way the various source volumes are handled, in particular the way Nav and Media volume are controlled. Navigation volume can now be adjusted separately from the media volume simply by turning the volume knob while the nav is "speaking." However, due to the way the E39 and E53 DSP audio systems work (volume is controlled in the amp, not the head unit) this new feature WILL NOT work in DSP equipped cars. In order for nav audio to be properly heard in these cars some extra setup is required.
1: In the SOUND menu turn DSP mode off (unchecked),
2: Use the STEERING WHEEL volume control to turn the DSP amp volume all the way down to avoid damaging speakers.
3: Play some music and set the DYNAVIN's volume to about half way on the displayed volume scale using the volume knob. Since the DSP amp is turned down you should not hear anything.
4: Using the steering wheel volume knob turn up the DSP amp volume until you can comfortably hear the audio but its not loud.
5: Set the voice volume within iGo volume settings to about 1/3 of its range. The"master volume" should be set to maximum.
6: When you touch the voice volume slider or change voices you will hear the nav voice speak. While the nav voice is heard, use the dynavin's volume knob to adjust the volume to match the volume of the music. When you are adjusting the nav volume the volume scale at the top of the screen will turn green instead of red.
7: Once satisfied that the music and nav volume are similar use the STEERING WHEEL controls to turn the volume all the way down.
8: Turn the Dynavin's volume knob until the onscreen volume display shows between 50%-75% (how high you set the volume here will set the systems maximum output level)
9: Go back to the Dynavin's sound menu and turn on DSP mode. This will "lock in" the relative volume levels and return volume control to the DSP amp.
10: Slowly turn the volume back up using the steering wheel controls, if it does not go loud enough use the DSP level adjustment to gain more output. If you cant get enough output uncheck the DSP box and go back to step 8 and turn the volume to a higher setting.
You can still use the volume settings within the iGo menu to tune the nav volume to taste if needed, same as its always been.
To be clear, what we are doing here is getting all of the volume settings close to even within the Dynavin system, since the volume in a DSP system is actually a function of the cars amplifier....we have to get all the volume settings evened out BEFORE we check the DSP box and turn volume control over to the amp.
Now if you followed all of that go ahead and update.....
if you didnt understand, I dont recommend you do this update. "
