Motorola uses a non-Microsoft Bluetooth Manager. You should ask your question on one of the more technical cell phone boards, but don't be too hopeful. You should expect to purchase other mapping software for your smartphone, now that Pocket Streets has been discontinued.
This is one of the major annoyances of the Windows Mobile platform, actually. You can't depend on OS functionality to be there on every phone. Random stuff is missing or disabled -- the GPS intermediate driver, Remote Desktop, create new file in Pocket Word and Excel, etc.
