I have a Treo 700p.
On normal calls the car works perfectly with the Treo (which is much more than I could say about my Motorola bluetooth headset).
However, if there is an alert on the Treo screen (such as a reminder, etc.) and a call comes in, the car's speaker rings and the display indicates a call, but when I try to answer the call (touching the off hook button on steering wheel), nothing happens. I have to go to the Treo and clear the alert before the call answer function works.
I never had this behavior with the Motorola headset.
Any clues?
Thanks!
