Yes, this is annoying. I just gave up on long strings like that, but I will start thinking about it again.
Question for you: Does the pause and wait functions work properly in those strings? I think my BlackBerry is not being sent the right signals to respect those functions from the LEXUS.
The pause function seems to work, and I haven't tried the wait function. It would be nice if you could run the first set of characters under one phone book address with a wait function, then the second set with another phone book address.
