I’ve had 4 custom autosounds over the years, two now. One got sold with the car, one failed early and the local dealer replaced it at a large discount. I find the LED readout difficult to see, and the push pull controls confusing to remember. I shut the battery off in the cars, and the old ones don’t carry the memory over. But I’ve not found any replacements that weren’t a lot of money.
Expensive ones
