Sk-swm3 trav'ler pro refurbished
This system replaced an older trav'ler that failed to find and lock onto satellites. Upon removal, I discovered that a broken tooth on the ring gear was the probable cause. The new pro was easy to install using my orig8nal baseplate/wiring and finds/locks onto satellites very fast with the GPS. My only issue was in setting up the idu. The instructions included must have been from an earlier version idu but I found the correct instructions online.
