This Grom Auxiliary adapter was the solution to my car stereo needs. The 2005 Toyota Sienna XLE is not equipped with an aux input on the JBL/Panasonic 6 CD changer unit. The CDs were an OK solution until the changer ate my CDs. At that point, I was limited to AM, FM and cassette!. I took a chance on this unit and I don't regret it. The stereo in this car is one of the best that I have ever heard (and I am picky) This Grom adapter has very good sound quality. I plug in a laptop with Media Monkey and 500GB of FLAC music files, put it on shuffle and I have a nearly infinite variety of CD quality music for my long haul trips. I never have to load a CD again. My Wife's Sandisk MP3 Player also plays FLACs and has similar sound quality. MP3s don't sound good under any circumstances, so I avoid them.
Replacement Radios offered the adapter at the same price as the Grom website, but offered free shipping. The unit arrived fast, installed fast and worked to my satisfaction. I will consider using them again when I decide to do the Grom Blue tooth upgrade.
