Since your system does not see the phone at all any more, I would suspect a hard failure--something as simple as a connector came loose on the phone interface box in the left rear quarter panel.
If I try my steering wheel phone button without the phone installed, it does see the phone components, because the dashboard asks me if the phone is installed. Yours isn't even seeing the permanently installed parts of the phone stuff.
LOL.
I have taken delivery on 11/28/2000 of a new X5 4.4 with a BMW CPT 7000 TDMA digital phone (AT&T digital one rate plan). The phone worked correctly for four days both as a portable and as an in-vehicle "hands free" installation. Today, I took the time to step through phone's owner manual. When I was operating the phone through the On-Board Monitor (also used for the nav system) the phone system became non-operative. Initially the "telephone" function became "greyed" out on the OBM. I was unable to use the phone in any manner while installed in the ejector box. When I removed the Star-Tac phone from the ejector box, it worked fine. When I placed the Star-Tac (while powered on) into the ejector box, the handheld display immediately stated "Powering off" and then promptly did so. When I removed the Star-Tac from the ejector box the phone was then able to resume normal operation. Hoping for a time-out counter or "soft reset", I left the car for ten minutes. Now the "telephone" function doesn't even appear in the OBM and the Star-Tac stays powered on (but completely inoperative as a "hands free" phone) when plugged in. I strongly suspect a software bug in the X5. Does anyone know how to reset the on-board software so I don't have to waste time at the dealer on Monday?
