  If your LG Car Receiver isn't turning on, first, double-check all the connections to ensure they are correctly and securely connected. If the connections are fine, the fuse might be blown. Fix the issue that caused the fuse to blow, and then replace it with a fuse of the same rating. Then, turn the unit off and on. Also, noise and other factors may cause the built-in microprocessor to operate incorrectly.

Why can't I tune into radio stations on my LG Car Receiver?

  David ChapmanAug 29, 2025
  If you're unable to tune into radio stations on your LG Car Receiver, it could be because the signal strength of the stations is too weak when tuning in with automatic tuning. Try tuning in the stations manually. Also, if no station has been preset or preset stations have been cleared when tuning by scanning preset stations, preset the stations.
