Viper 4706v vs 5706v: Which Starter is for you?

2 remote start alarm systems compared

It's reasonable to believe that someone had invented the remote start systems for automobiles in northern climes, where people hated trekking through the snow to sit in ice-cold cabins while their cars warmed up. A wired remote starter was sold as early as 1966 by a company in Winnipeg, Canada. A Chicago company, Ramostar, advertised a radio-controlled remote starter in 1968 issues of Popular Science. The Ramostar Radio Motor Starter sold for $595, for about a third the price of a new car.

Today, remote start systems are dealer upgrades for new cars. Many people take them for granted. It’s good to get into a warm car on an icy winter morning, or a cold car on a blazing-hot summer afternoon.

The Viper 4706v and 5706v bring remote start capabilities – and more – to those who didn’t get the feature installed by the dealer.

Viper LCD 2-Way Remote Start System

Viper’s 4706v is pretty fancy for a remote starter. It comes with the Responder LC3 remote control, which features an LCD screen for controlling functions and reporting the car’s status.The Responder LC3 screen includes icons and text labels for user functions. Viper software puts the most famous images in the center of the screen dynamically depending on context. If you like, you can set the screen to display the temperature inside the car’s cabin so you can delay entering the car until it’s just right. Viper says the remote communicates with the car from a mile away.

This doesn’t implement security features. There’s no siren sound if someone tries to break into the car, and no alert chirp or on-screen indication if someone is tampering with the car after you’ve left it parked. It does, however, implement remote lock and unlock features, including popping open the trunk – a handy feature if your arms are full of bundles.

The system is also compatible with Viper’s VSM350 SmartStart module, which lets you use your smartphone as a remote.

Viper LCD 2-Way Security + Remote Start System

Viper’s 5706v is identical to the 4706v except in one important way: It adds security to its list of functions.

With the 5706v, the Responder LC3 remote will let you know immediately, playing a siren tone. The LCD will tell you precisely what happened: for example, it'll alert you if someone had tripped the shock sensors, indicating that another car may have bumped yours in the parking lot.

You can also choose to mute the car’s siren and route all alerts to the remote.

All the other features are just the same as those of the 4706v, including the ability to control two cars with the same remote and the optional module to use a smartphone as a remote control.

Choosing between the 4706v and the 5706v is relatively straightforward. Both systems handle remote starting and keyless entry with a two-way remote featuring an informative LCD. The difference is the security feature. If you want it, the 5706v is the better choice. If not, stick with the 4706v.

The 5706v usually sells for around the same price as a 4706. You may find different prices from another retailer. But if the price is the same or even close, then you might as well go with the 5706v. It does more for a similar price – it is clearly the better value.
