Dude, Where's My Radio Presets??
 

Weird one - daughter who uses my RVR claims the radio presets simply "disappeared". Static or off-channels where the faves once were. Battery was not disconnected, nor anything else remotely close. Anyone ever hear of such a thing?

Also, the manual says you can store 12 FM stations - that does not seem possible on my 6 buttons. ?

FM1, FM2. 2 x 6 =12. Moreover, you may store with the same 6 buttons 6 AM stations too (18 presets total). Joke aside, the FM frequency range is broken into two sub-ranges. Just use the mode button to cycle between AM/FM1/FM2/CD/USB/BT etc.

As for loosing presets without battery power outage is really strange. First, check whether your clock is off or not. If so, your battery is to blame (short?). I assume you have not done any modifications involving pulling the wiring harness. One of the wires (mostly the yellow) must have constant voltage to keep the settings. A faulty device may have been connected to the same circuit . One other remote possibility is accidentally picking up a transient inductive noise. A Xenon arc lamp (not automotive) ignition routinely made a USB mouse to freeze up on a laptop and the radio presets to drop on a car radio in use nearby. I am not sure you will get better than wild guesses, like mines. If the problem is reoccurring I would check the integrity of the circuits.

Well, I will take a wild guess. Your pre set stations may have been on FM1 and now your on FM2.

Nope! Discovered it. Think "youngster randomly pushing buttons"... ;)
