I have a new 06 GS300 and I would love to do this mod on my car. I'm in New York City (Queens). Anyone remotely close-by who will be willing to do this for me for a fee? I have no idea how to solder, and ground, etc. etc., so I'd rather just pay someone else. let me know: digg1er at hot mail dot com. cheers.
Are there any known side effects of performing this mod? any at all? will the navigation satellite signal be less responsive or slower at all? I know the warranty is voided, but I don't care about that. (They would never find out about it if done right)
