The local Lexus dealer wanted over $1000 to provide the amplifier not including installation costs which would have been another hundred or $200 probably. The amplifier went out of production years ago and a used one would have been provided. I was able to procure the amplifier for $200 and installed it myself. The amplifier arrived within a few days of purchase and was perfect. I now have radio sound once again and I am quite happy with the amplifier and the person from whom it was purchased.
