Review on Metra 40 SIRXM Satellite Antenna Adapter by Gregory Sirgio

Based on our own experience this antenna adapter just doesn't work properly. We were excited to finally have satellite radio in our car, but the Metra 40 SIRXM failed to deliver .The installation process was confusing and time-consuming. Even after following the instructions, we couldn't get a consistent signal. The only positive aspect was the affordable price, but even that doesn't matter if the product doesn't work. In short, avoid this Automotive accessory and look for better alternatives..
