Just came from the dealership for the free oil change (free for as long as you own the new car purchase) and they did a software update to the head unit. This caused the head unit to loose all my radio station presets and my Bluetooth connection to my phone.
Couldn't factory and aftermarket head units store radio station presets in a section of memory that won't be wiped clean by a battery disconnection or software update? Televisions don't loose the station presets when the power goes out nor when there's a software update so why does this still happen with car head units? My factory unit has 12 FM presets and 6 AM presets and yes they were all set. Spent the last several minutes sitting in my car restoring those presets (since I won't try that while driving) after arriving home. Also had to reconnect my phone's Bluetooth to the head unit. I'm ok with that part since it's so easy, but reprogramming the presets is more difficult since I only have certain station numbers memorized. Had to go looking for those other stations.
I'm no electronic engineer, but couldn't this be an easy problem to fix?

There's no good reason why that isn't the case with modern systems. I'll bet they have people who've even thought of tucking system parameters into a bit of memory--or even make it downloadable into a flash drive...except that it would cost a few bucks to implement and it can't be said to increase sales.

Not an easy problem to fix with your existing radio, but an easy issue to resolve in a future version of the radio. I also think this is the problem with an engineer mindset. They look at it from an engineer perspective and not so much an end user perspective.
Didn't have this problem with the old pull button and shove it in hard form of radio presets. Sure, you still needed to turn the dial to fine tune the reception, but you were at the area of your station when you pressed that button.
Honestly, if they loaded a new firmware on the unit, it's possible the presets would be lost no matter what. Going to depend on the way the radio is made and the procedure for loading FW.
Now that I think about it my newest car, Kia Forte5, has a built in hard drive for saving songs internally. And when I disconnect the battery it does not lose fm or sat presets or bluetooth or other settings. So it must be writing those values to the hard drive.
