jonasy Posted Monday at 08:34 PM Report Share Posted Monday at 08:34 PM hi, all I tried two 2019 ST with B&O sound system, they should be identical on everything but their B&O sound system sounds so different. they both have original setup and no modification. i tried to play same sound track on my thumb drive, set the treble-mid-bass....everything the same. what could be the reason? the amp? one was built in Apr. 2019, the other was Oct. of 2019. thanks Quote Link to comment Share on other sites More sharing options...
Haz Posted yesterday at 03:27 PM Report Share Posted yesterday at 03:27 PM (edited) Welcome to the Forum @jonasy! It's possible that the two 2019 Edge STs do not have the same software level in their B&O 12-speaker audio system's Audio Digital Signal Processing (DSP) modules. While I'm unable to remotely view DSP software levels in 2019 model year vehicles, I checked the DSP software level in a B&O-equipped 2021 Edge ST with its last DSP update (JL3T-14C589-EA) having occurred in September 2021, and a DSP update is presently available for that specific vehicle. In the case of the 2019 Edge STs, one vehicle may have received a DSP software update that the other vehicle has not yet received. The DSP module is located behind the Driver's Side (Left Hand) Cargo Loadspace trim panel... Good luck!

Haz Posted 23 hours ago Report Share Posted 23 hours ago Looking at the 2021 Edge ST's history, it appears its previous DSP update did not occur through a dealership visit, so it may have been Over-The-Air (OTA), like the January 2025 SYNC4 update which is clearly identified as OTA. How long this vehicle has been waiting to receive its presently available DSP update is not clear, since I cannot view the 2021 Edge's Connected Vehicle status, which shows a 60-day history. If you are not a FordPass user, you may want to explore its capabilities. OTA software updates can sometimes become stalled as a result of unsuccessful update actions toward other prerequisite modules. The surest way to navigate multiple-module updates is to have the dealer connect the vehicle to Ford's software update server, which assesses and properly sequences the software updates. If problems arise, then the dealership can contact the Dealer Software Support Hotline (DSSH) for guidance to overcome the problem. Good luck!
