Why Buy from Max Marine Electronics?

We’ve sold hundreds of NAVnet displays and systems and have the expertise to evaluate, service, and rebuild these units to avoid common (and rare) issues like LCD degradation, backlight failure, trackball wear, and glass/bezel separation.

Every NAVnet display we sell undergoes an extensive inspection and service process, including:

New LCD installation when necessary
Reconditioned backlight PCB installation (for CCFL-backlit versions)
Trackball and housing cleaning/servicing
Case seal cleaning/re-greasing
Bezel inspection for warping; securing the viewing window to the bezel
Updating software to the latest version
This attention to detail ensures each unit we ship is reliable, fully functional, and built to last.

This VX1 RDP-139 has been fully tested in-house and confirmed to be 100 percent operational. The photos shown are of the actual unit—no stock images are used.

*This unit shows signs of past usage (please see photos). They are cosmetic and do not affect the machine’s operation at all.*

Our RDP-139 and RDP-149 units do not include optional boards such as ARP11, NTSC/PAL, or RGB video output. These boards are always removed before sale and must be purchased separately. Buyers are responsible for verifying which option boards are installed in their current system before purchase. We’re happy to assist with identifying these to ensure compatibility and a smooth transition.

This listing is for the RDP-139 display only. Testing peripherals such as the GPS antenna, radar, and sounder are not included. This unit was originally flush-mounted. A mounting bracket is not included, but brackets and knobs are available for purchase separately—just ask.

This is a C-MAP version and is not compatible with Navionics chart cards. It can be converted to Navionics after purchase. If you’d like us to perform the conversion before shipping, please let us know. Otherwise, the buyer is responsible for any return shipping costs associated with post-sale conversion.
