got the 771 and im happy with it
I just needed remote start but the alarm and keyless entry was a plus
I got mine installed at best buy (yeha yeah yeah)
the installer was good and got it done right the first time.
Talk to the installer first.
The alarm is only as good as the installer.
The range is good ,I dont understad te need for the 1+mile remote start.
I mainly remote start my car only once a day,in the morning and im at home.
My car is about 400' away and it works great.
Works in the office to and im in the middle of the builing,no windows.
For longer range I have found that sticking your hand in the air and pointing the remote towads the car helps alot
any other questions just ask
