This is deeper than i ever imagined. And no, i havent done that. I'll try to see if I can find some video tutorial on how to do that though.That may be a major parasitic draw and absolutely not normal behavior for a new vehicle. This means the navigation system is preventing the body control module and other related systems from entering their proper low power sleep cycle. Have you tried measuring the amperage draw at the negative battery terminal after letting the car sit for 30 mins?
It can be an intimidating test if you haven't done it before. Be certain the multimeter you use is rated for at least 10 amps and that the test leads are in the correct ports for an amperage reading. Many people accidentally blow the meter's internal fuse on their 1st try.This is deeper than i ever imagined. And no, i havent done that.

Tech is becoming too huge that i dont think manufacturers are ready for. They should balance everything and still prioritize longevity.Modern infotainment systems are becoming the biggest parasitic drains in vehicles. Automakers focus so much on flashy tech, they overlook basic reliability, I mean... a navigation system killing your battery overnight shouldn't even be possible, yet here we are
Thanks, thats a great heads-up. I'll check my multimeter before diving in., did you find a specific draw from your nav system when you tested it, or was it part of a bigger parasitic drain issue? Just trying to figure out if mine's acting up alone or if I should be looking at other modules too.It can be an intimidating test if you haven't done it before.

My previous posts were based on general electrical diagnostic principles, not a specific problem I personally experienced with a nav system. The parasitic draw test is how you will determine if the navigation unit is the sole issue or part of a larger problem. After you get a baseline reading, the next logical step is to isolate the draw by pulling fuses one by one from the interior fuse box. What was the baseline milliamp reading you measured after the vehicle sat for half an hour?Thanks, thats a great heads-up.
