After about 6 months of trying to figure out why my Palm Treo 700p
sometimes acts funky in my 335i, I think i found a way to correct it when
it does.

Problem I was having was my treo would pair fine but would act funny at
times, the major problem was that it would always mute the radio, but
sometimes i couldn't use the hands-free or hear the phone through the
speakers.  i found that incoming calls would normally work fine but when i
dialed out i had to use the handset.

by trial and error i found that i could reset it to work properly by:

1. turn car off, remove key
2. turn off bluetooth on treo
3. reset/reboot treo by removing the battery, wait for it to fully restart
4. turn on bluetooth on treo
5. start car

i tried while driving by turning off bluetooth in the car and then going
through steps 2-4 and found it sometimes works, but its worth a try when
i'm on the highway and don't want to pull over just deal with my treo.

i think that most of the problems occur after i sync my treo with my pc
(i'm not convinced yet that its the only time), something must get reset in
the process - so now i just go through steps 2-4 after each sync and things
seem to be working fine

hope this helps anyone with a similar problem!
