Gummy and SlimKay have full GPS and Bluetooth capabilities. The unofficial CM builds are FAR more stable than the official ones, so if you must use CM, go with an unofficial like Mastamoon or KitKang.
HOWEVER... every custom rom has issues with a 'kill signal' with Bluetooth, so if you use BT, you need to make sure you power down the other device, before you try to turn off BT on your phone; that will send the signal to your device and unpair the two. Otherwise, your phone won't be able to reconnect to BT on that device and you'll have to reboot. It's a known bug and people are working on it.
I used Gummy all December and now I'm running SlimKat... they're stable for daily use. I'd recommend a custom kernel with Slim, though... I'm using Lean Kernel.
