    What to do if my JRC NWZ-4740 power does not turn on?
    • S
      Sharon WilliamsAug 4, 2025
      If your JRC GPS unit isn't powering on, there could be several reasons. First, check the cabling from the junction box to ensure power is being supplied. Also, verify the power supply unit cabling if you're using optional power supply equipment. If the cabling is fine, inspect the fuse connected to the power cable and the fuse in the optional power supply equipment, replacing them if blown. If none of these steps work, the display unit switch might be broken, in which case you should consult with JRC or an affiliate.
