Saw this item on eBay and wondered if it would be better than the Sirius XM V200 Connect Vehicle tuner. To install the tuner I reluctantly had to cut off the plastic clip on my stock antenna so that I could plug it into the tuner. I attempted asking the seller how the device worked and installed but receivedan automated message stating the seller receiveda high volume of messages and does not have time to answer them. Has anyone seen or installed this item? I'm assuming from the connectors, it's a simple plug-n-play into my Kenwood head unit and factory Sirius XM tuner?
