Cadillac Audio, Video and Security Systems Discussion, 2002 DTS Bose/Nav "can not load software" in Item Specific Cadillac Discussion; I have an 02 DTS and the screen on my nave is stuck open and displays "Caution cannot load system ...
The lithium battery is located on the left side of the DVD unit (about 1/3 height) where there is that seam in the case. Well you actually need to open it up to get to the battery and you need a soldering gun to have it removed/replaced. The thing is, what you hope to achieve with that? Yes your lithium battery is dead and the firmware was lost so you need to replace the battery to keep the firmware in memory, but FIRST and fore most is to get the firmware burned on a CD (CD not DVD) so it can be loaded into the unit.
With no firmware the unit ONLY accept/ejects disks in the first 5-10 seconds after it is powered on so don’t get frustrated with it, now you know how it works.
Unless you load the firmware the screen will not retract. To load the firmware is a 3 minutes deal.
The message you see on the screen is because the disk inside the unit is not the install disk (probably you are trying the navigation disk-no that’s not it, you need the firmware disk).
