I just bought a 2009 G6 and my wife wanted to know if I could install back up sensors on the car. Was this an option? If so it may not be too difficult. If not has anyone got any information on the subject? I see after market kits but I really do not want to modify to much. I have installed alarm/keyless systems on other cars so I could do it. If it was an option then I might be able to get plug in parts.
