Have '03 LS430. Unable to get Link-Sys removed several years ago for free and now will cost a bundle at Lexus service. Does anyone know how to disconnect or stop Link - Sys welcome and error messages at each start-up. Have removed back-up battery in trunk area and disconnected main battery for several minutes but still have the voices. Any suggestions?? DEM

 

disconect the batery, open the trunk on the right hand side there is an indentation in the side of the car, lift up the carpet there shuld be 5 or 6 10mm bolts, take them out, un plug the lexus link.
