New gps

[340DA]

My 340DA has the original Garmin (Black & white) GPS system. The antenna for the existing system is mounted on the radar arch.

I want to replace the existing system with a new Garmin GPS, possibly with the Garmin GPSMAP® 740/740s.

Can anyone tell me how difficult is it to snake the antenna cable for the new system from the dashboard to the top of the radar arch?

It's super easy. Shouldn't take you more than an hour to do a nice clean job. Get yourself a metal coathanger and use it to pull the cable through all the corners. I've done it twice now.
Enjoy your new GPS.
