I'm glad everything is working as it should with the SiLabs radio. I'm getting really close to releasing the next version of DriveLine. Unfortunately, SNO let me know that XM functionality is broken. And I'm not sure when or how I broke it. So I've gotta try to get that fixed. If anyone needs SiLabs functionality right now, PM me and I'll send you a link to download a test-version of DriveLine.
