Satellite radio is supposed to be available in late summer. There is supposed to be a module available That will hook up as a retrofit for most late model car headunits. I am not talking about an fm modulator kit like when CD's first came out. I can't find out any info whether or not The head unit in the tl has aux. inputs for such a device. I know the frequency is in like 2.4GhZ. What type of antenna will be needed. Any info will be appreciated. wv5b@aol.com
