cellphone reception
The integrated mv-60 phone shows good reception on its screen, but the command system shows little or no service, the dealer can't find anything wrong and suggests an "antenna booster." Any ideas?

If you get an indication that the phone is initializing, then your system is recognizing the phone. Problem isn't with COMAND, head unit, PSE or cradle.
If you get "no phone" then it isn't recognizing it. Problem likely one of the above.
If your system recognizes the phone and it initializes (downloads the phone book) but you get no signal strength, you may have a problem in the antenna system, as the dealer suggests. One potential failure point is the linear compensator (a low-powered amplifier that makes up for line loss - e.g., what the dealer may have referred to as an antenna booster).
Another possible problem is the antenna switch, a device that switches the antenna from the cell phone to the Tele-Aid unit (if you have one).
You may be able to determine which parts your car needs from the phone bulletins at http://home.earthlink.net/~phdwebsit..._bulletins.htm
Given that your car is new, it should be under warranty. If anyone has a similar problem with a car out of warranty, such parts are MUCH less expensive on e-Bay.

Thanks. The phone initializes ok, but loses reception in the cradle - goes from 5 bars to fewer, and loses service in areas that the phone is ok if you remove the phone from the cradle. The teleaid works ok. One of the problems is that the dealership is in an area where it works ok, when you testdrive it the phone fails, so the serviceman is having a problem duplicating it in the service bay.

The sevice person should take a look at the phone manual, there are some pretty good diagnostic tests in there, even if the service area is located next to a tower (our location is next to a tower and customers always have good reception there, but when there was a problem the signal strength still goes down 1 bar).
I would recommend looking at the adapter cables included with the phone kit (I believe there is one in the CLS kit; can't remember for sure). Motorola now has them made in China and they are really poor quality. Checking them with a meter is the best test, as visual inspection does not always reveal flaws.
