Title: NO Lag, works perfectly!
Review: There have been several reviews describing a lag between pushing the button and getting a response on the unit. I installed this on my '05 Buick Rainier (GMT360 body - same as Trailblazer, Envoy, Ascender, etc) controlling a DNX9140. I made sure the connections are tight and programming done correctly - the result was a perfect install with no lag on single button presses at all. As a test, I pushed the Volume Up button 10 times in very quick succession and the unit registered 8 of them...not bad at all.Also, you have to visit their website to get vehicle-specific instructions (this is because the SWI-Jack is compatible with almost a hundred different cars) [...]. Installation was not bad at all. The hardest part was getting to GM's control wire under the steering wheel. Programming took all of 2 minutes.Overall, I give this 5 stars, and recommend it to anyone who has steering wheel radio buttons.
