Umm, depends really on what you're trying to do. The factory system is good but it can be better. I have a nice stereo sytem and plan on getting aftermarket wheels. A good alarm would have a tilt sensor which would go off if anyone was jacking up your car to steal the wheels and a proximity zone. A soft chirp would warn person if they got to close to car. I'm also thinking about installing an internal "pain" siren so if anyone does get inside and tries to get my clarion deck they're going to go deaf in the process.Northern Rider said:Question: What are the shortcomings of the factory system?
Just about any alarm on the market has those options. I have personal experience with Compustar and DEI Viper alarms. Both have treated my friends and myself well. No major issues. The compustar has amazing range. I've been with my friend when his alarm notified him of proximity in a mall atleast a mile away. Its a neat feature, but if the alarm isn't adjusted and installed properly, very annoying.415_300C said:rogue what do you recommend for an upgrade that would include remote start and tilt and proximity sensors?
We are running a Pro 8000 in ours. It's equilavent to the APS996a from Prestige. It has remote-start, paging, locks, trunk, cell call, lights, temperature check and more.bigwise1 said:
