My car has been inactive for about a month while umichchris and the RepublicWerks crew did their magic on my beast. When I fired her up for the first time today, I noticed my SAT radio is stuck on "Acquiring" and will not pick up a signal. FM and AM work perfectly with strong signals. Anybody come across this problem before? SAT worked just fine before I disconnected the battery. Trying to avoid a trip to the dealer

Check that the SDARS is connected tot he Sirius tuner. Typically, if the radio is not "Acquiring Signal" it is an antenna connection issue.







SDARS (SATELLITE DIGITAL AUDIO RADIO SYSTEM)

The SDARS is a separate tuner for digital reception. SDARS receives the data in terrestrial form or via satellite. Two antennas are installed for reception. One antenna is for terrestrial reception and the other is for digital reception.
If the satellite reception is disrupted, SDARS automatically switches to AM/FM reception. The loss of quality between digital radio and the standard AM/FM radio can be heard clearly.
Digital radio

Digital radio means that a much higher number of stations can be picked up. In addition to the audio data, other information is also broadcast. The sound quality is close to that of a CD or MD.
Control

If the satellite radio optional extra is installed, the AM/FM receiver is decoded in the headunit. In this case, the SDARS is controlled via the MOST bus by the headunit (radio/M-ASK/CCC).
Reception

To enable AM/FM and satellite reception, two antennas are connected to the SDARS.

  • SDARS antenna for terrestrial reception: This antenna is responsible for reception of AM/FM signals. It has the same function as the antenna on a conventional radio
  • SDARS antenna for satellite reception: This antenna is responsible for reception of the digital signal. This signal is transmitted from a satellite to the vehicle.
