Hi Jon,
I had the same problem, heres what to do, if you have the code, if you have not got the code IT IS THE LAST 3 DIGITS OF YOUR CHASSIS NUMBER
1. Switch ignition to "ACC" position.
2. Press and hold button1,6,and the power button.
3. In thr radio display will appear "SEC".
4. Push and hold "Tune " button upwards and press button "1".
5.You should now see "---" in the radio display.
6.Press button "1" to enter the first digit of your code, Button "2" for the second digit and button "3" for the third digit.
7.Press the number repeatedly until the desired number appears e.g. if your code is 246 you will need to press button "1" three times as the numbers start at "0" button "2" five times and button "3" seven times.
8.Once your CORRECT code is entered on the display press and hold "SCAN" until the radio switches off.
9.Switching it back on should now be operating as normal.
9a. If after pressing "SCAN" the message "ERR" appears followed by a number then you have entered the wrong code, the following number will indicate the number of wrong attempts you have made, go back to step 4.
WARNING, The wrong code mat be entered up to 9 times, DO NOT ENTER THE THE WRONG CODE FOR THE 10TH TIME AS THIS WIL DISABLE THE RADIO AND THE DISPLAY WILL READ "HELP" AND LOCK OUT THE RADIO FOR GOOD, CONTACT LEXUS FOR HELP.
