I’m no longer able to make calls out

I’m no longer able to make calls out or in with my mobile when paired to my car?

Have you tried to re-pair the phone?

I have a similar issue with my NX350h when using Android Auto. I need to exit AA and connect via Bluetooth then reconnect to AA, once I've done that it's fine, until the next trip.

If you have an Iphone, I found a recent update stopped me being able to view text messages on my 17 CT200h system, an iOS update fixed it / works as normal now. A re pair didn’t work before. Didn’t need to re pair to get it working once updated it just worked again.

I had the same problem with a Nokia smartphone, that had worked for a few years, then started to have problems both calling out and answering calls. Sometimes it worked and sometimes it didn't. Changed the phone for a Samsung one and the problem went away.

So, worth trying a different phone if you can to see if that is where the problem lies. Obviously the CT200h will have an older version of Bluetooth in it, but later versions found in current smartphones are supposed to be backward compatible.
