Not sure on the 460 side, but on the LX570/LC side a lot of the issues were with the integrated HVAC controls and cameras...people got it all working eventually, but I didn't get the sense it was a turn-key plug and play operation.
My understanding is that it hijacks the USB input so it's just another 'source' everything else is intact. There are some obvious/not-obvious pieces of that, that you can't use satellite radio with it at the same time as they're separate sources, but anything within the android OS should work...
