Let me know what you think of the system on down the road and if you ever have any issues. Or perhaps if the unit has any quirks that you haven't discovered yet. I'm seriously considering the ST960 from them as I want all the smart key functionality. I just think it's the modern way to go and it's one thing I've always wished my T4R had.
Check this out guys:
ST-960
And since I already carry my key fob in my pocket separate from my keys... it'll be just perfect. Maybe... minus the fact that it's $480...
