Guido: I assume you're from Brisbane after seeing a few of your post. Give Chris Rogers a call at www.audioexpress.com.au . He'll most likely recommend autowatch for you. I got the M80 (forgot which exact model) at that time and got an autoelectrician to hoook it up for me. Everything works fine and its slightly cheaper than what Chris quoted for the Autowatch (both brands are Australian standard complied) but I'm not very happy with the detection range. If I'm 5-10metres away, it will not sense it at all (just shits when it comes to sensing range). For the amount that I'm saving (around 200), I would opt for tha Autowatch if I were to have it done again. Unless you're feeling rich, then get the gps tracking ones.
