mid-to-late 2000s cadillac navigation systems

This actually isn't just about Cadillac but all luxury cars from the 2005-2012 era.

I'm an unabashed Garmin GPS nerd, and own way too many Garmin nuvi, Drive and DriveSmart screens. Example: I own 3 of 4 of the current line, Drive 53, DriveSmart 66 and DriveSmart 76, with the only one I don't have being the DriveSmart 86). And that's just the newer stuff. I have many older ones going all the way back to the mid-2000s.

And this brings me to navigation systems luxury cars and trucks of that era were using.

Updating the maps on a navigation system offered by Cadillac or any other luxury brand is basically impossible. And what really ticks me off are the reasons why. There are two.

First, the map data is DVD-based, and I know exactly why. It's because all the luxury automakers went cheap. SD and CompactFlash storage obviously did exist, and either could have been used instead of DVD. But nope, didn't happen.

Second, the map data was engineered to such an ultra-proprietary degree that it was never even considered the nav system might be used beyond a lease term. They were all engineered as a one-and-done. "Update map data? What? Are you NUTS?!"

I can take any Garmin nuvi from the late 2000s, generate new data images from OpenStreetMap data and update the maps. Not a problem. Been doing it for years at this point. The exact same should be possible on a 2005-2012 luxury car nav system, except it isn't. Those systems are completely locked to DVD-only, completed locked to ultra-proprietary map data, and there's not a damned thing that can be done about it.

Now you know why Android head units sell. You either take apart your mid-to-late 2000s luxury car interior and install one of those, or you just buy a Garmin like one mentioned above and go with that.

This makes me wonder how long it's going to take before an automaker releases a car with no screens and uses that as a selling point. To be more specific, no touchscreens. I know the backup camera has to exist because of Federal Motor Vehicle Safety Standard No. 111. But there isn't any requirement for infotainment nor a touchscreen to be present. Automakers could junk that crap if they wanted to. And they should.
