Have you got Mouse Keys turned on?

macOS Sierra: Control the pointer using Mouse Keys

I would check if it(car) should not be in pairing mode before it can be paired

they do this so random people don't pair their phone with random cars for a laugh

well, I shut down and restarted the computer. It was a mess until I again shut bluetooth off. when I turned it back on, it responded to the JBL.

so now it's working again. problem solved

Very true. Didn’t give enough info.

Issue resolved. Thanks for your reply.

try an SMC reset. It sometimes makes errant hardware straighten up and fly right. There is no downside risk.

Hi

Whilst some users have reported success with pairing Apple Watch with certain car Bluetooth systems, Apple advises that iPhone, iPad and iPod touch are the only devices that are designed for use with car audio systems.

Apple Watch can be paired with compatible Bluetooth headphones and Bluetooth speakers, but it is not designed to be paired with car audio systems:

• Use Bluetooth accessories with Apple Watch - Apple Support
• Listen to music on your Apple Watch - Apple Support

If you would like to submit a feature request to Apple, then you can do so here:

• Feedback - Apple Watch - Apple

Tap on the small "i" in the circle at the right of the device name. Tap "Forget This Device".

I leave it on always also.

Though everyone is free to turn if off if they wish. No reason I can see to do so.

Hi

No - Wi-Fi must also be enabled:
