The Ford unit is a plug in. Anything else (such as Viper) will require wire splicing, relays, etc. Seen many problems with the new Super Duties and aftermarket alarms and remote starts triggering codes and PATS issues.
Installation is the easiest thing ever. Requires the base security module (part #: DL3Z-19A361-A), the RMU unit (part #: DL3Z-19A390-B), and RFR antenna if the truck was not originally equipped with factory remote start (part #: DA8Z-15603-A).
The base security module plugs into the DLC (AKA: OBDII port). The RMU antenna plugs into the base security module. The RFR antenna plugs into the TPMS behind the glove box.
Dealer activation is required. Not only does it require IDS, but it also requires dealer-only activation of the RMU, which can only be performed by a dealer service technician with proper access. Most outside of a Ford dealership will not have access to this.
Functions include lock, unlock, panic, and remote start. The security module upgrades the factory perimeter alarm to include dual-stage shock sensor. The security system can also be set up to text or email the user in the event of the alarm being triggered. It's detailed enough to tell you if the door was opened or if the shock sensor was set off.
All functions require 3G/4G data network. So it doesn't work in all areas. It piggy-backs mostly the AT&T network in most areas. Keep that in mind. It's great in some areas, sucks in others where AT&T is weak or nonexistent. However, as long as there is a signal, the range is unlimited and response is extremely quick. Typical response time is just under 5 seconds from press of a button to vehicle receiving signal. About as fast as sending a text message.
Service is about $50 a year for unlimited use. Pretty much the same as most aftermarket kits.
If the truck sits for a period of time, the unit will go into sleep mode to preserve battery life. The system can be scheduled to turn back on at a specific date and time. Make sure you schedule wakeup at least 24 hours in advance as the system pings the network only once every 12 hours in sleep mode.
Compatible with iPhone and Android. You can load multiple vehicles per phone, and multiple phones per vehicle (with correct login and password info of course).
All remote start parameters, including runtime, HVAC, etc are controlled in the driver information display in the vehicle dash. The system ties in directly to the vehicle without overriding or hacking anything. Run time can be set as high as 15 minutes, and a maximum of 2 remote starts are allowed before a key cycle is required (max 30 minutes).
I think that pretty much covers it. Overall it's a great system. I train dealers on how to install, activate, and troubleshoot these systems, so if you guys have questions feel free to ask. There's hardly ever any problems out of these other than in areas where signals are weak. Average dealer installed price is about $800. A dealer quoting $1,400 as mentioned earlier in this thread is way overpriced. Highway robbery if you ask me.
Hope this helps.
