Hi - almost ready to buy an A119. I've been looking thru the forum for simple answer to question: "Is the parking mode/survelliance on the A119 useful or not?" I see that you have to "turn it on" so that's something else to remember. Some say these features just don't work very well to begin with. And, you would have to buy a hardwire kit that would support parking surveillance (e.g., Spytech 10'Hardwire for A119 + Fuse Kit" - $12.95 Amazon) - BUT....if I wasn't planning on using parking surveillance I should just order a Spytec 10' Hardwire for A119 ($9.95). I get the impression that parking surveillance just isn't that useful and I should therefore keep it simple with the wiring kit but if it does work, I am interested. (I won't being doing the wiring - don't worry). Thanks for the perspective - so many things to think about..... DT
