Removal of the player is the first step. Now, you have to disassemble it sufficiently to get the errant disc back into the magazine. You will want to remove the magazine after the disc has been returned to check for damaged parts. Otherwise, the problem will happen again.

The most common issue I had is ground wires, I would also suggest changing it as quickly as possible. The other problem I had is adjusting a GPS navigator for my motorcycle. For this I would recommend checking this page https://yourmotobro.com/best-motorcycle-gps/ because some models require more than just adjusting a pair of screws on handlebars.

My car (2005 Honda CRV) was shipped overseas and the radio asked for a code. After several tries, I searched the internet for a solution. Apparently Honda now allows you to obtain the code through their provided website. You will need the VIN #, the phone number and zip code that is on file when you purchased the car. Our car was purchased used and did not come with a manual. When I went to enter the code in I had already entered too many tries, now it reads ERROR E.

However, even before having the code (as well as now that it reads ERROR E) I can get the radio working. Push in preset buttons 1 and 6 and push in the power button simultaneously. A long number appears - at that point I pushed preset button 2 and the radio operated normally. Unfortunately, I do need to do this each time I turn the radio on.

The Q factor does have to do with tones and pitches of your music. This determines a Quality factor of how pitches are placed (high tones, low tones, and mid tones) and using the Q factor will use a preset setting to put the tones at a high proformance audio.

Simple test and trick for you.

  1. Put in your favorite cd.
  2. Turn on the Q factor
  3. Play a song and listen to it for atleast 45 seconds
  4. turn off the Q factot
  5. Play that same song for atleast 45 seconds
  6. Now you determine if the quality used by the Q factor is better or worse

For some songs that have close pitch audio, it may not be as noticeable, so you can repeat and test. Give it a try, because then you can understand it more by hearing then reading. Its all about how you want it to sound. Good luck

Thank You
