No sound since dead battery....

[Pip vellfire]

Hi guys, headunit issue, just want to see if it's happened to anyone else or if they have any ideas.

 

I have an original headunit (Japanese) but I am connected via Bluetooth.

 

Before the battery died I had sound from what was on my phone going through the sound system.

 

However now it's not giving me any sound. It works and gives sound when I use one of my daughter's CD's.

 

I have deleted the Bluetooth from my phone and the phone from the headunit and then reconnected, but still no sound, the phone plays (Spotify) and says it's connected to the car but nothing out of the sound system.

 

It's a Nhzn-x62g 76051

 

Any settings ideas from anyone?
