Ive recently purchased a Honda City 2010 and have installed a tracker in it provided by Tacking World (Pvt) Ltd. Its also comprehensively insured. The issue however remains of the "audible" Alarm System. The car does not have one and I cant get the "peace of mind" without an audible Alarm System (Logic: better to be aware of anyone tampering with your car "as" it happens rather than waiting till "tracker" co. calls you). The Honda people have clearly told me that the vehicle's warranty will stand terminated if any wires are cut.Honestly I dont care about the warranty any more than I care for my "peace of mind" (warranty is rarely used in any case), so I have decided to install an audible Alarm System. However, I need expert advice in the following areas:-- Does it mess with the ECU (or car computer in local lingo)?- Does it have any (-ve) effect on the tracking device installed in the car?- Recommend a good Alarm System.- Recommend a good place to buy.People with tracker & alarm combos, please come forward and advise.Thanks.
