Works as described. The Zone2 out does not work on my Clarion Max7700 navi. Make sure to check you model number and compatibility before buying!
I connected this bluetooth receiver to audio in inputs and now I can listen to my music with great sound fidelity wirelessly! (ELECOM エレコム iPhone6s/6s Plus対応 Bluetooth オーディオレシーバーBOX NFCペアリング機能対応 LBT-AVWAR500)
