WEll ... let me give you more details

The GPS is a Raytheon 398 and works great.
The chart plotter is a Raytheon 601 ( I have 2 of these units)

The Radar is a Raytheon R41 XX

THe 601 puts the chart (only the chart) on the radar screen

it works great for about 30-45 seconds then seems to lock up. But...
I can move the cross-hairs on the chart plotter and the rest of the
chart plotter (only the chart plotter) LOCKS UP TIGHT

Everything else works fine

any thoughts?

Thanks
Mark

Hi all

I have this issue
I have done a hard reset on both units

The Raychart puts the chart on the radar screen ok but after about 30
seconds, the chart plotting seems to lock up. With the exception of ,
you can still move the cross-hairs and only the cross hairs. no other
button on the 601 does anything except the power button

If you power off and then back on the 601, it will work fine for abut
30 more seconds.

ANy thoughts?

Thanks
Mark

How does your gps work on it's own? If it is fine then the trouble is
most
likely in the gps connection to the raychart or the C-Map cartridge being
used.

I always had good results dealing with the techs from Raymarine. Maybe
you
can shoot them an email and they can give you some troubleshooting tips.



Again, I would check the hard wire connection between the gps and the chart
plotter, and for a defective C-Map cartridge. Does radar show up OK on the
same screen?
