Anybody with a Viper Smart Start on a 2012 X5?

Anybody with a Viper Smart Start on a 2012 X5? I've read several threads on Remote Starts already but I'm looking for more recent feedback.

I have a 2012 X5 and have made it two winters without a Remote Start, but this winter is just nasty BS in the Northeast, especially with a new born! Single digits for an entire week makes for miserable mornings getting the kids to daycare!

I have installed Viper systems in the past back in my younger years driving non BMW's, and I know that they really do this right, but based on my past experience installing these things in my own vehicles, I'm just wondering how this could even work in the X5. The heat, the seat warmers, the defrost are all electronic, non-analog, controls that would make me believe that any I/O would be difficult to control?

Not to mention, what does this do to my warranty? Does it really void it?

There's a really professional car audio shop not to far from me that has installed my radar in my X5. They do really nice work with luxury cars from BMW's to Ferrari's and I trust them with my vehicle, unlike the clowns at Best Buy, just wondering, if anybody has ventured down this path before.

Is it really even possible? Is it worth the risk?

If you paid someone to install a radar detector, this is WAY beyond you capabilities.

And it is almost impossible!

It has nothing to do with the seat heaters nor non-analog controls... The issue is that the car requires the physical key fob to be 'seen' in the car to allow starting. And if you spoof that, the car is essentially unlocked/insecure.

And yes, if you were to hack up the electronis to fool the car into thinking the key was there, to allow a remote starter to work, if anything went wrong with the CAS (car access system) BMW would not warrant it any longer.
Keep it as simple as possible...but no simpler.
