Is there anyone in the Dallas / Ft. Worth area that has a VAG-COM and can help me downgrade the software version on my RNS-510?

I installed firmware version 1140. I previously had version 1040 installed. I see no improvements and I am getting errors with the satellite radio now every time I start my car. I get one of the three following error messages every time the system starts - 1) Antenna Error, 2) Updating Channels, or 3) GCI Update.

Also the song/artist title will not update until I change the channel after each restart. Once I have changed the channel a single time, the song/artist title updates correctly.

I need to revert back to version 1040.

Please PM me and let me know if you can help. I can pay you for your time.

Thank you.
