When we bought the boat we update with Raytheon as the the original still worked so we kept the old installedas back up ssecondary as common with long range coastal blue water boats. I like the stand alone with back up. The reason is the screen on many bundled are to clutter with stuff and have to toggle back and forth between applications.
The original old radar I took out to have more helm space area. So we should replace the radar for back up. Iwill pprobably replace with a bundled capable but only buy the radar and maybe the electronic chart ad we presently have one electric chart. But would stay with stand alone beside I am cheap and old.
