I installed JustDrive via iTunes App Store, launched the app on my iPhone, signed in with one of my Google accounts. I don't know why it needs a Google or Facebook account, its navigation seems to use Apple Maps APIs since SIRI voice is used. Anyway, I recommend use a gmail account that does not have any sensitive personal information just to be safe. I then followed the steps to set up my account. Once the setup was done, I switched to InControl app on the iPhone and arranged the app positions. Finally I connected my iPhone to DS via USB cable, tap InControl in the Infotainment screen, and JustDrive icon showed up.
I did not spend too much time playing with it, but my first impression is that it is much easier to find places/addresses then DS' navigation feature (to find an address on DS, you have to enter separate city, house number, etc, for JustDrive you can simply speak the entire address). Phone call feature works okay, but I don't see any advantages over DS' own phone feature yet (the search actually is slower than DS’ own Phone feature). Media Play is pretty good, it can search any media titles on your iPhone.
The main control method for JustDrive is the Voice command, and it is inconvenient since you have to stretch your arm and tap the microphone icon on the screen in order to start the voice command.
UI is not bad, the wait time for the response is a bit slow in some of its functions (round trips between the DS’ InControl and JustDrive on the phone). Overall, it's not bad, but I can pretty much accomplish all of its functions via DS' own infotainment system, except the better search function in JustDrive.
My friend used his phone and took a few pictures while we were playing with JustDrive last night. Sorry about the bad image quality:
