This remote starter is a great value with all the necessary functions that most people desire. Great transmit range on the FOBs. I installed this remote starter on my 2010 Focus. This was a simple installation on my Focus (once I was able to locate the vehilce's wire locations). That part took me longer than expected since this was my 1st remote starter installation. I paired this Viper 4103XV with the Omega OL-MDB-ALL bypass module. After performing the 3rd remote start (so that I could verify the safety shutdown operations) the engine shut off and set off the car alarm. I noticed that the LED light on the Omega had gone off. The Viper was no longer communicating with the Omega module. The customer support for Omega is terrific! They were able to help me determin that the data bus from the Viper remote start was not sending good data to the Omega bypass module. I had to remove the data mode cable and install the hardwire connector. FYI: If you ever need to know which wire from the Viper 4103XV remote starter is the "grounded while running" ouput: It is the BLUE wire (Pin #1) on the 4-pin satellite harness. It is labeled "(-) 200mA STATUS OUTPUT". You will need to connect this wire to the Omega's "grounded while running" input when using the hardwire mode.
