u/A_Matter_of_Change

I recently got a new stereo head from Amazon -China because factory touchscreen stopped working. I have a 2016 Jeep Patriot. I bought used. Uconnect Bluetooth. When I bought it, Bluetooth music had a 6 second delay and phone calls were great. Now that I got the new stereo head, it's the opposite. Music plays fine but now I have a delay in phone calls. I cannot, for the life of me find any info on solving this but maybe I'm not use the right key words.

Is it a wiring issue, possibly?

I've tried everything, I think. Updated software, connected/ reconnected...

Help!!
