The head unit certainly leaves a whole lot to be desired. It's pretty laggy and I agree the sound isn't that great.
Agreed and I've just started thinking about replacing the HU on my 2021 premium. There are a number of vehicle settings only accessible through the HU, lights, defogger, doorlocks... are these all lost with an aftermarket HU? I believe the Maestro modules only allow the retention of steering wheel audio controls.

Good question - Crutchfield has info on Forester HU replacements. You may want to give them a call, their support is very good.

In my 2020 Premium, I believe the settings you mention can be adjusted using controls on the steering wheel, along with the display between the tachometer and speedometer.
The one thing I haven't been able to adjust, after installing a Kenwood head unit, is the clock on the center-dash display - so I just cover it with some painter's tape during the part of the year when it's 1 hour off from the clock on the radio (which does update for changing DST - probably due to the Bluetooth connection to my phone).
With the iDataLink Maestro firmware now updated to support Foresters newer than 2018, I'm going to have mine installed - to enable the OBD and steering wheel interfaces.
I have no idea whether the OBD serial bus interface connects to the center dash module which contains the clock.

I have the updated iDataLink Maestro and Pioneer head unit. Just FYI, my secondary display has always shown the correct time.
The Starlink Telematics Unit was removed from my car, along with the stock radio.
Does your car still have the Telematics Unit installed - and do you think it may be what's keeping your clock correct, even during DST time changes?

Well, just before the temperature dropped to around 20°F here in Houston, I bought a new battery for my car.
A coworker helped replace the stock battery, and when we finished, the clock on the center-dash display was no longer one hour off --- it's now something like 5 hours and 20 minutes wrong, with no way to set it. :unsure:
