I am a new owner of 2012 Nissan Rogue SV.
I am thinking of getting a remote start + keyless entry system.
Do you have any recommendation on which one to get?

Many of the systems allow trunk release and additional aux to be connected to the remote. The trunk release can only be opened by pressing a button on the trunk. There is no button inside the car for trunk release. Is it possible to controll the trunk release with the remote starter remote?

Do you have any recommendation on what else to connect to the remote start? I was thinking the rear defogger (if it is possible), a/c, windows and/or dome light.

Some of the remote start systems come with additional alarm system. Since the Rogue SV already has an alarm system, is it worth getting a combined remote start/keyless entry/alarm system?

If the remote start system is professionally installed by a mechanic or alarm/remote start installer will there be any negative impact on the Nissan factory warranty? I did not see anything in the documentation.

i have prestige alarm remote starter pretty cheaper than viper does the same.
