This device works great on my fancy JVC stereo. I had to read a lot to figure out how all these different adapters (HD ready, Bluetooth ready, Sat ready...etc) work.
However, the instructions are misleading. You must have 32bit Windows XP to program the adapter to match your stereo connections. The adapter cable you purchase separately is only the beginning. The order is this: 1. Go to Audiovox.com to get program and install it. 2. Connect SAT adapter and apply driver. 3. Run SAT adapter update (like firmware) that tells your adapter how your brand-name car stereo thinks. It is simple but the online instructions are a bit out of order. WinXP 64Bit will give driver errors!!! Had to whip out the ancient laptop with 32bit XP on it. But it works!
