Anyone had trouble w/a 2003 325I XM install using the Blitzsafe box? I plugged it in last night & got the error msg "NO SDARS". XM technical support folks were clueless and I tried the vendor help tip of checking the country setting on the radio. It would seem that the head unit isn't recognizing the receiver, but it initially flashes Sirius & then XM Radio like advertised. Any thoughts/suggestions?
