I am happy to say that my experience using Bimmer Tech was extremely positive. The service was provided as advertised. More importantly the staff that I interacted with were extremely helpful. All e-mails were answered in a timely way; even after the service had been rendered and payment was made.
In summary I would say that their service was a #1.
I would not hesitate to business with them then again or to recommend their company to others.
I subsequently dealt with the sirus radio due to channels that I thought should have been included in the package. During the conversation I told them that I had the upgrade performed at a BMW dealer. They were abe to fix the issue -- the upgade that was done by Bimmer-tech was transparent to them. I continue to enjoy my one years worth of services.
