1. I am hoping someone can help me identify the location and part number for the Bluetooth module for my 06 XKR. It worked famously with my previous iPhone's (now have an iPhone 7 and it paired fine with it also) then just packed up a few months ago. Based on other threads it would appear my Bluetooth module has stopped working and needs replacement. I have no idea where it is located in the car and would love to buy the new part and replace it myself. Please help if you can. Thanks in advance.

2. The other irritating issue I have is the auto trim feature for the steering wheel (out and down) works intermittently. It usually comes out but not down. Weird? Sometimes it works fine. But recently it has stopped. I can maneuver it manually using the side switch but the automatic portion is problematic. I'm wondering about the part that would control this feature and again where it is located and can it be easily replaced. Thank you.
