Viper 5904 vs 5704

I want to get a viper remote start and am leanin toward the 5704 then getting the app/equipment for my phone. But I was curious as to what's the major difference between the 5704 and the 5904. And what's the more popular and better reviewed.

 

I'm 90% sure the only difference is the 5904 has an "HD" color screen on the remote and the 5704 has a non-HD screen. See the pictures below. They have rechargeable batteries in them that you have to plug in to charge every so often. I bet the 5904 needs to charge more often due to the HD color display; but that's just a guess.

There could be other differences I'm not aware of, but if they're are I'd bet they're pretty minor. If you get the 5704, I did a write up on how to install one in a Tacoma here.

What features are you looking for in an alarm/remote start system besides the smartphone app?
