Both battery cables are on snugly and I don't have any other weird issues with radio or climate control, just the nav unit cutting in and out. I use Android auto for actual directions, I just like the oem unit for the charm

I own a 2008 USDM Spec b, and a few months ago whole I was driving the oem nav went black, flashed the Subaru logo a few times, then stayed black for the rest of the drive. It does this Everytime I drive the car. While the screen is black and the headlights are off, the buttons below the screen blink 4 times, wait a few seconds, then blink 4 times again, repeating for the whole time the car is on. I've only seen a mention of this "code 4" on one other post, and there was no more info on it. I think the old nav unit is cool, and I do not want to replace it with an Android tablet like many here have. I have taken it out of the car and inspected the connects and the PCB, and I haven't noticed anything out of the ordinary. I tried emailing Subaru for more info, and if course I was just told to bring it to a dealer. Any info is greatly appreciated
