I have an 8700c from Cingular, and can tell you from personal experience, I have found Telenav to be awesome. I bought the BT puck that they sell and appreciate the ease in which it can be moved from one vehicle to another. The family and I took a trip to Los Angeles and I took it with me. Got me from Woodland Hills to LAX to Santa Monica to .. the mall..
The one thing that drives me nuts is that, unless you're close to a turn, it shows the direction you're suppose to go and that's it.. I appreciate seeing the overhead map as you come up to a turn...
So the Telenav service works well? Does it automatically change the screen as you make the turn or do you have to hit a button? How large are the instructions? Also, did you just have to buy the puck ($89.99) and pay the $9.99/month? Or do you have to buy extra software, etc. to use it.
I've used Google Maps to get basic directions, but it's not useful as a driving aid.
I always wonder if it wouldn't be worth spending slightly more to have a standalone GPS navigation system (Garmin c320), given the larger screen and purpose-built functionality.
I have a hard time paying 10 bucks a month for something I don't use every day. I mean if I really want to get directions I can always use my laptop. I am just looking for something that is a little more spontanous. I carry my BB everyday. Is there any software only solutions?
jcricket: bought the $89 puck and am paying the $10/month service.. We just relocated to Columbus, OH from Austin, TX -- so we're still getting used to the city and this helps... I was using Google Maps, but hated having to press the "3" key while driving to get to the next turn.
bianchina3: The 8700 doesn't have a GPS receiver built in, so I had to buy a receiver... Plus, the puck is small enough that you can carry it around if need be.
