Voice directions on the BlackBerry were full and often gave compound instructions when turns followed in close succession. The Highlight's service seemed to be trying to issue compound instructions, but often the second part cut off after "and then"; it also left off many street suffixes, neglecting to say "Parkway" or "Street." The BlackBerry's service was more explicit in announcing highways, too. It said to enter "Route 3 East", whereas the Highlight's service said only "Route 3."
The BlackBerry Bold's AT&T Navigator service lets you use speech to enter an address or to search for a local restaurant or gas station. The voice-recognition feature needed no training and was quite accurate. On the Highlight, I had to input data via the numeric keyboard--a tedious, time-consuming task that was too distracting to attempt while driving.
The services I tried on the Samsung Highlight and the BlackBerry Bold provided a good text-to-speech navigation experience, but the AT&T Navigator service on the BlackBerry did better, thanks to a more powerful platform and new software and features.

Check These, Too
You have (at most) three choices for cloud-based navigation: Google, Networks in Motion, and TeleNav. Your cell phone provider may offer only one service for the device you own. Networks in Motion products are available exclusively through carriers, and sometimes carry brand names other than NIM. TeleNav's products may be branded as TeleNav or with the carrier's name. The Verizon VZ Navigator and Sprint AAA Mobile services rely on Networks in Motion's technology, while AT&T Navigator, Sprint Navigation, and T-Mobile TeleNav GPS Navigator work with TeleNav. Google Maps is free to use on supported handsets.
