Worked for me
2006 Toyota Camry
Crutchfield Customer Review (What's this?)
This kit eliminates the need to cut & solder wires for the steering wheel control box. I didn't realize this required power and ground connections until after I was finished with the radio harness (had to go back and add another splice...my bad). The connector for the factory harness does not "snap" in (looks like to should) so I wrapped it with tape to hold it. Seems to work fine.
Pros: Fairly simple install
Cons: Connector does not "snap"
