GSI is told that SIRIUS is reworking the FM Transmitters in PNP units. As we know the new Sportster 4 has a much weaker FM Transmitter, and is not letting you use 87.7 and 87.9FM like older SIRIUS PNP units have. We are told the next shipment of Starmates, Sportsters IR, SIRIUS one, and S50 will have a much weaker FM wireless Transmitter, and will not let you use 87.7 and 87.9FM. The is because of the FCC looking at the power of FM wireless Transmitters for both SIRIUS and XM..
If you notice shop.sirius.com is also "out of stock" of every radio with a built in FM Transmitter.
