Thankyou...first of all mybsystem was not an upgrade...the wkm,lkm 900 etc was new from arizona distributer and hand picked up from them by my dealer and than shipped to me 3 weeks ago.I had to remove google from host files to get program to come up.Serial # is visable along with one waypoint enabled statement in tools section of wkm assistant.Both lkms show red status along with blinking green status light on airboure unit and solid green on ground.Center antenna pin on airbourne unit looks short compared to ground pin...but think its still making good electrical contact with rubber duckie antenna...k
