I'm currently living in ft. Lauderdale/ Miami so no parking spot is a good one. I'm only concerned because it is a nice touchscreen navigation system
What's up! I'm in Miami Lakes so I know exactly what you mean... Listen, do yourself a favor and go grab an alarm with proximity sensors and long-range or paging remotes. There's a bunch on craigslist locally and some of the sellers are also installers. If you need help, let me know and I'll help you look for a good one.
Also, make sure you change the codes on your remotes/alarm once the installer is done. A buddy of mine took his new 2013 Camaro to a local shop and they stole his car the next day. When they caught the thief (thru lojack), it was actually the installer who made himself an extra remote and had pre-hotwired the car!! As good practice, any 'good' installer should be able to teach you how to reprogram the alarm on your own.
One question, what unit is it? I assume it's not detachable?
