Gerry C - I would like more information on your viper solution. We had a viper remote start put on our original 2012 NVP at Best Buy. I remember at the time it was REALLY HARD for them to figure it out, but they eventually did and it worked pretty well. Door locks were controlled and remote start on the key fob was reliable about 75% of the time, up to around 1000 feet. I did NOT have to install a viper alarm though. Do you know if their new smart start system, including smart phone control, would work and if it would require an alarm too? We have since replaced that van with a 2015 and I miss being able to pre-cool the vehicle. I filled out an inquiry form on the viper website but no one has contacted me. Any insight is appreciated.
