One problem is that the Denso programmers are all Japanese and the GM platform engineers are all American, the Denso guys are genius but much is getting lost in translation and so forth, they'll get it right (eventually).

 

ZX..defenitely let us know about an upgrade path for the nav units. The idea of having seperate audio settings for each input would be great for me.. XM radio is a bit muffled (good ol sat radio compression) so I crank up the treble on it. This kills the sound for CDs, etc..so Im constantly changing the damn settings.

 

Ditto here. Thought I was doing something wrong. Can't wait for the update.

 

ZX, have you heard anything about this update for the radio that they are working on? Thanks.

 

Has anyone been able to have their radio successfully updated to fix the problems stated here? It is annoying having to change the EQ each time i want to set it for a different source.

 

sounds like once it's in talk mode you can only switch out by touching an adjustment button. Doesn't say anything about it going back to an already set, custom one. If I change sources it will pick up where that source was set before (old setting saved). If I hit the TALK button that is the new setting for what I'm on but shouldn't effect other sources right?... You read it and tell me????

Quote from manual (appendage for Nav unit)...

Automatic Equalization
If the system has automatic equalization, you can
select customized equalization settings designed
for Talk. Touch the Talk screen button to hear
the change in sound. The system will save
the setting for each source.
To not use the automatic equalization setting,
press any of the screen buttons that will change
the treble, midrange, bass, balance, or fade.
This will take the system out of the equalization
setting so that you can create your own sound.

I've read this 5 times and get a different opinion each time. Now I think you can customize the talk setting only??? ARGH

My 6 disc in dash DOES IN FACT save for each source. I'm now convinced the NAV does NOT.

 

The problem is that my Nav unit does not maintain EQ settings for each source. If I set it for a specific source, it sets it that way for every source. I was wondering if anyone else with this problem had the dealer successfully update the radio software to fix it.

 

Where is the AMP located??

 

I have a 2007 LT without the Bose system, standard radio non Nav. As for the option codes I do not have the Bose amp. What do I have?

Thanks for any info.
