Powering Up I have a Rca mp3 M202C and when I Hold the ON Button it Goes ON but as soon as I release it it turns OFF.

does this one have just one button to turn cruise on and off.
If so it sounds like the switch needs to be replaced

I have had several remotes; 1 was RCA. Resetting the remote was the same on all - 1. turn TV on, 2. press and hold code search button until light goes on (some flash, others stay on), then release 3. press TV button, release once light goes on 4. press on button every 10 seconds or until TV turns off - up to 100 times pressing button!! 4. press enter . Now the test... turn TV on - good luck

If the set does not play then powering alone will not solve the issue as the processor is faulty. check and see if a reset can solve, if not the player must be connected to a PC and checked for error files/corrupt files , which must be removed formatted and re-installed.

Unplug the mp3 from the USB
press and hold the menu button for 10 seconds
release then press and hold the play button
-- while holding the play button plug it back in. Wait until it says intializing, then release the play button and press start.

Last night I replaced my battery and my unit would not go any further than the Pearl logo. So this morning I downloaded the firmware upgrade from http://voxrightnow.custhelp.com/app/answers/detail/a_id/2243/related/1, and followed all the troubleshooting instructions that popup when you start the program:

start the program,
remove the battery,
hold the play button while plugging into usb,
release the play button the the term "initalizing" replaces "searching",
click the start button to replace the firmware.

First, make sure the "Hold" button is not engaged on the side of the player. If it is not engaged, hold in the "+" button on the front of the Mp3 player before connecting the mp3 player to the computer. Continue holding in the + button while connecting the mp3 player to the computer. After continuing to hold the + button for an additional 10-15 seconds, a window should pop up on your computer screen that says "Found New Hardware Wizard." Proceed with the rest of the steps, and the computer should soon be recognizing your mp3 player again.

potential battery issue

My daughter's was doing this. We found out that there is a button on the side of the player that says hold. She had turned it on hold, by accident. As soon as we turned it off, it worked fine. This "hold" button is for when pocketing it, so the battery doesn't run down.

The M button is for the menu. Hold it down and the menu should pop up. As for the memory card, look for a standard SD card near in the camera/USB drive section of a department store.

Was the SD card in the MP3 player when you loaded the songs or did you load them some other way?  You may have to first put the SD card in the MP3 player first, then load the songs onto the player.
