Hi, I just installed a new Sirius "E" receiver to match my (US Version) RNS-E (I swapped out my old Sirius receiver which was not compatible with the RNS-E). I can now receive all stations. However, when I change channels I get a brief error message on the RNS-E: "ANNTENNA. A technical problem occurred. Contact your Audi dealer for support." It displays for about 2 seconds before it (successfully) changes the channel. The delay is annoying and the error message is concerning. Has anyone else installed a new Sirius receiver? How has yours worked? Any suggestions? Thanks.
