I’m having an issue diagnosing a navigation system problem on my 2002 LS430. I’ve gone a few years with the GPS link not working, which means it no longer receives a satellite signal and defaults to dead-reckoning mode (the GPS symbol disappears on the touchscreen). It’s a nuisance issue but it’s low on my priorities.
It also happens that I’ve been using a dashcam for the last four years. I never linked the two together until I had a couple of dashcams go bad in 2016, and spent the whole summer without one. Well, my GPS started working again, and I chalked it up to a warm summer fixing some sort of electrical wiring fault in the antenna.
Once I got my fourth dashcam in September, I noticed my GPS stopped working again. It was getting cold in the mornings and I thought my good luck spell had ended. Then, it occurred to me that maybe the GPS gets disabled when the 12V was in use. I’ve since found that it’s true for all three of my 12-volt ports (cigarette lighter, arm rest, rear seat cigarette lighter).
None of my other electrical loads (seat heaters, defrosters, seat massagers, headlights, fridge, etc) seem to trigger this issue, and I replaced the car battery in 2013.
So, what’s my next step? Is this a grounding issue? Voltage issue? A conspiracy of aftermarket electronics deliberately disabling automotive functionality?
The city of St Petersburg, Florida uses camera systems sold by American Traffic Solutions (ATS, formerly American Traffic Systems) to issue tickets to drivers allegedly running red lights. According to The Newspaper, when the activists at St Petersburg Red Light Cameras reviewed logs of the 21,602 photo tickets issued in the city from October 29, 2011 to April 30, 2012 they discovered that the ATS cameras were reporting that they “measured” Bugatti Veyron level speeds from cars not realistically capable of that kind of velocity.
The city council in Mukilteo, Washington voted on Monday to reverse itself on the issue of photo enforcement. After over 1909 voters signed a petition to call for an election to ban red light cameras and speed cameras, council members began to have second thoughts about their contract with American Traffic Solutions (ATS) to operate automated ticketing machines. ATS also operates in the neighboring town of Lynnwood.
