Update:
I've been looking around for iPad mounts. At first, I was thinking of going with a moveable/retractable one, but then I realized that there is nothing on the market that looks good, is functionable and is not ridiculously priced. Not only that, but it will just be too much for a car... So I've decided to go with a regular mount. Preferably one that can be hidden when placing the stock top cover back on. It will take some minor modifications, but I'll probably go with something like
this. It's affordable, simple and can be modified to fit a car.
If anyone have any suggestions, let me know.
