Living in the city surrounded by tall buildings without any real view of the big blue sky, it takes a long time for my 9500i to acquire GPS signal as I am driving out for a trip so my local false signals always go off. Also my 9500i is mounted under the headliner without a clear view of the sky. I really don't want to move it. I have tried the ferrite choke trick with some success, but I'm still to inpatient to wait the usual one minute for GPS acquisition from a cold start, but that's only if my car isn't moving that much and has a relatively good view of the sky. Otherwise, it can take over 15 minutes or more.
Well, I decided to hardwire it to a constant on source so the GPS signal is always ready to go if I leave the detector on. Nice thing about the auto brightness of the LED display, it really is not noticeable at night time, especially where it's mounted high. Anyway, I can just flip my visor over the detector.
How long will my detector last? How many hours of use is it rated for? If it burns out or gets stolen, I will have an excuse to get the 9500ci.
