A Technical Service Bulletin (TSB) is issued by an automobile manufacturer when a specific problem on a vehicle has been identified. It provides the manufacturer's instructions on how to correct the problem.
I think the amplifier is under the front passenger seat. To fix the bluetooth phone connection problem the amplifier must be replaced with a newer one. You will have to take your vehicle to a Lexus or Toyota dealer/service center, give them the TSB number (AU001-04), and request that they replace the amplifier. However, it may no longer be covered under warranty.
