Hi All, i have a problem with a little stereo project i'm trying out. and looking for ideas or help.

Car was fitted from factory with pro sat nav, carver dsp and 644 phone prep & Aux. (i added a Grom usb3)

The screen started to play up due to broken casing, and thought rather then buy another antique with sh*te sat nav i would look at an alternative. So i removed the screen and stereo and replaced with a business stereo and a Garmin drivesmart 65 alexa.

The Garmin connects via stereo aux,so i have full sat nav guidance, amazon alexa screamed music & phone via the stereo including full voice control for nav, music & phone

The problem i have though is....the Grom unit seems to show up in the business stereo display ok and allows changing etc but i have NO sound from this what so ever. ( Grom sound works ok with the pro nav stereo but obviously no display)

Anyone have any ideas. Spoke to grom technical ande they have no idea?

Also can anyone with a business stereo / dsp advise how you change the dsp settings.

Just for reference i have also disconnected the 644 bluetooth module incase of conflict but that didnt work.
