03 Es300 Aftermarket Radio Install in 92 - 06 Lexus ES250/300/330 Posted September 8, 2010 · Report reply I am about to embark on this mission. I'm adding GPS and possibly a backup camera to my '04 ES330. Any tips on where to mount the backup camera would be helpful. Also pictures are extremely helpful. Thanks in advance and thanks OP for all the information and part numbers used.
