    Angry 2007 NAV system

    I took delivery of a 2007 DTS yesterday and have a problem with the NAV system. The display stays lit (blank) all the time. If you turn it off with the display button the radio comes on. If you turn the radio off with its power knob the NAV screen lights up again. Is there a way to turn off the lit screen? Also if you turn on the NAV system the radio comes on. I would appreciate any help with this. Thanks

    Here is what I do with my 2006 DTS Performance. It should also work for 2007. Turn on the radio and select audio menu. Press display and select turn off display. Now you will have the radio and NAV on with a blank screen. Then what I do is press the radio mute button on the steering wheel to silence the radio. I agree that with everything off (radio and NAV) at night with the backlight is very irritating.

    Thanks for your reply. it does work. It is disappointing that Cadillac had this problem in 2006 and never fixed it. I think that they should find a way to reprogram the Nav system so that we do not have to use a work-around to make the system usable. If Cadillac cannot make it work properly I am going to ask for as refund of my $2000.

    Dealers might have played with it during prep and changed something. I have seem that happen before.

    Warning: GM as a sales promotion will give the Navigation system for free with the purchase of the DTS. And that is what it is worth. I have checked with everyone I can reach in GM and also contacted the OEM in Japan and found out the following. When you turn on the Nav system the radio will also come on. If this is distracting when you are searching for an address you have to turn the volume down. The screen is always lit and if it is too bright at night you have to turn down the brightness and contrast controls. When you want to see the map you have to readjust the controls. It is safer and easier to use a paper map.

    In 8,000 miles I have never needed a hardcopy map. Crude thou the implementation may be, I can drag you kivking and screaming into the 2000s.

    You are missing the point, GM not only is cutting back on personal but on their product as well. They bought the cheap version of a Navigation/radio system. They left out some circuits so the user has to do the work. Look at the Lexus system and compare how they work.
