Don't know why you would delete it, it's a great bit of kit I didn't think I'd buy into it but certainly did.
Even after 4 weeks ownership - I would have quite happily have deleted it if I was getting the money back.
I still prefer the look of real dials. Though I have been driving with real dials for well over 3 decades.
The thing I am struggling most with on my new car is keyless. I still keep reaching up beside the steering wheel to switch the car off. I even forgot to lock the car once.

Now I always look at it to see if the mirrors are in!
