What is the difference between the DA/DX and the latest? What improvements were made? Currently my DA/DX works very well, and my only disappointment is that I must wait for it to index every time I start the car. Other than that, it stays on random and remembers the last input I selected. If there is no major improvement over the DA/DX, I will just wait until there is a significant change and ask for the upgrade then.
Still not quite done.
