08 C300 dumb UMI question..

I got my 08 C300 this weekend and saw an iPod, aux, and USB cable in the glove box. After coming on here and finding out you have to access it in the CD menu I finally figured it out and got the ipod to play. Few questions:

1) I see people mention UMI Nav+4, are there two versions? I'm not sure mine has navigation. At least not that I've figured out...

2) One of the sources it lists is bluetooth streaming - I paired my iPhone 5S to the car itself with no problem, but when I try to stream it just says "looking for devices" or something to that effect. It's never once connected. Am I missing something?

How do I know if I have Nav? I found the UMI, big back box near the passenger knee bolster behind the carpet, two plugs on either side and a blue antenna connection and a purple antenna connection.

Any insight would be greatly appreciated.

That's UMI/NAV20. That's the only device for pre facelift 204 that supports BT audio.
To start navigation screen, press the "C" button for 2-3 sec next to the audio controller.

The 'controller' the volume knob? I saw in some instruction I found online it said press CLR for 2-3 seconds but that didn't do anything.

The device I have has the grey part in the glovebox that goes in place of the light. I saw a YouTube video and it's exactly what I had (searched c300 UMI on Google and saw that video). I suspect I have navigation, but I just don't know if I'm hitting the right button.

Yes, the CLR knob next to the audio controller in front of the armrest.
Does "Navigation" appear in the speedos upper menu?

It works! Sort of...

Map doesn't show anything and i entered a destination and it says "waiting for GPS". I'm out in the open, so I have a clear shot. I know sat radio works, but maybe an antenna issue?

I didn't notice anything about navigation on the speedo though...
