Viper 791xv upgrade

Listen to what everyone here is saying, it's probably NOT the 791 which, BTW, has excellent range. If it was installed incorrectly then that WILL effect the range! The antenna wire cannot be bunched up! If it is you will have little range. have you checked this yourself? If the windshield has tint and/or excessive lead in the windshield like some foreign cars then that will also effect the range as well. Also check the battery meter on the remote, it should be good but if it isn't then range will be effected. Instead of just throwing money at the problem, instead make sure you got your moneys worth from whomever installed the unit. Don't assume they installed it correctly. They should be able to contact DEI directly for you and find out if your car has any problems regarding range when installed on YOUR windshield. There is NO reason why a PROPERLY installed 791xv shouldn't give you plenty of range. In other words, the problem most likely isn't the unit, but how it was installed or other outside factors. If you don't find out what these factors are, then you'll just end up spending more money with a 5900 that has bad range too.
