Let's clarify the issue:
From 2012 to about 2017, the Panda came with a radio, and, if Blue&Me was included, then there was a single USB and a single 'Aux in' socket on the dash near the gear lever (on the Cross is was a little further back nearer the handbrake)
From about 2017, all but the basic Panda came with a uConnect radio and a phone holder on the dash. Alongside the phone holder was a USB socket that only supplied power - no connection from it to the radio. But, inside the glovebox was a small box with a second USB socket on it (which could give power but also provided a connection to the radio for, say a wired music source or a USB stick with music files on it). There was also an Aux In socket there (3.5mm jack)
The issue that started this post was that from midway through 2018, that little box in the glovebox was dropped - you only had one USB socket (with both power and music connection), by the phone holder on the dash. This appears to be because (nearly) everyone now streams music using Bluetooth from the phone (and very likely from a cloud service liek Spotify) and so Fiat could save a few bob by leaving out the second USB connector.
So yes, if you have a pre 2017 car, you'll have a socket - either near the gealever or on the dash. And if you have a post 2017 (but pre August 2018) car, you'll have a socket in the glovebox too. The OP has I believe since had the ;missing' extra port in the glovebox added by the dealer.
