Bluetooth / Phone issue -- Fix

The bluetooth option in our 2005 Range Rover was incapable of working correctly. It was a bizarre thing. The Range Rover would ‘pair’ with our iPhones (or any other phone). When paired & someone calls, the # of the person will come onto the stereo system/nav screen & it would ring via the speakers. However, when you would answer the phone (be it by the phone, by the steering wheel or by the radio) there is no sound that will come through the speakers. The call is not disconnected but there is absolutely no sound whatsoever. Only if you choose a different source on the phone will you be able to use the phone but you would have to 'use the phone'; the bluetooth would not work past that point. And of course LRNA says the phones will work fine. But that was not the case.

Weeks ago, the truck spent hours at the dealer - they were trying to solve the issue as they had 'never heard about this particular issue'. I made another appointment (for something else) & they would continue to diagnose the problem then. Well, I scoured through this forum & various others until I found information... someone suggested replacing the PTI (personal telephone interface). So, I said that to the dealer. The service fella was like "no, no way because X, Y & Z work". Guess what? I brought it back in, they looked & could not figure it out. I asked again if they tried replacing the PTI, they said no & then told me that piece was ~$1,000... I then called the LR CPO phone # & they assured me that it would be covered. So, they installed it and - guess what - it solved the issue.

I'm fairly certain it's not just me that had the bluetooth issue. So, if you do... suppose there is a chance the fix would be the PTI module. Hope this helps someone.
