NXT Radar Dome upgrade

[Boatpro2]

I have a 3 year old NXT dome antenna and a 4 year old NavNet2 12 inch display. Screen shows 300 standby hours and 40 transmit hours. The radar didn't work this spring with an Azimuth error which I think means it needs a new motor. Question - Should I replace the motor or is there a newer antenna that might be better which still talks to the NavNet2? Thank you for your help. Rick

No newer dome radar than the DRS2DNXT, which would be a smaller dome with less resolution due to its smaller array size, if you have a DRS4DNXT. If you have the DRS4DNXT, I'd recommend simply replacing the motor.
