You can keep your official bluetooth off, roqyBluetooth works in parallel! roqy team provides all the software components (roqyGPS) to connect your iPod Touch / iPhone / iPad to a Bluetooth GPS receiver and benefit from any navigation software!
roqyBluetooth is available on Cydia package managers for jailbroken devices (ModMyI sources). There is now 2 versions of roqyBT:
