Hello,\n\nNew to Forum, have looked but could not see this specific issue.\n\nJust acquired a 2008 Yaris with detachable TomTom - a TNS400/410? no model number on the unit.\n\nIts proving slow to acquire satellites and several functions we'd like to change need to be accessed via Home on a PC.\n\nTried downloading from Tom Tom and kept tripping, so used the original disc and loaded Home onto PC. Everything started ok, then plugged in TT unit and the computer recognises it - but not Home. No matter what we do, Home continues to read No Device. If Home is off, connecting the unit doesnt open it. If open, Home doesnt recognise the unit - though the computer does.\n\nWent via loading My Drive - to get message unit no longer supported.\n\nNot all that bothered about map updates etc, but we would like to access the unit to set it up etc.\n\nAny advice, much appreciated.
