My apologies for bringing an old thread back to life but I've recently purchased a Zed and looking to get an alarm/gps Can anyone suggest something that they're using at the moment that is worth while? I am currently considering a particular one but from what I see/notice it only disarms via your phone. I'm looking for something that can be used with the cars central locking as well and not soley depended on the phone. The one I'm considering.. http://www.ebay.com.au/itm/191521204425?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
