Wow .. I was able to make a good connection ... I've since upgraded to the Bold, but the GPS connection software is the same for both units
The Blackberry Bold has the default option of the device GPS, but once the Delorme BT-20 device has been connected via bluetooth .. we then have the option to selected either device the onboard GPS device or the bluetooth GPS device.
PROS:... at this time ... It will connect with the Blackberry and provide GPS data
CONS.... at this time: .... getting the bluetooth to connect consistently and easily ... (Still testing this one .. Once connected the connection appears to hold just fine .. but once I intentionally break the bluetooth connection and attemp to reconnect ...it take about 15 to 20 min playing around with options to reconnect )
Still working on what causing the long delay on the reconnect ...
