What is the difference?
Just to emphasize, the door speakers are different. So, with the exception of the tweeters, you're buying a complete set of speakers.RPO code UQA adds the Pioneer amplifier in the trunk and a different set of speakers.
The configurations are stored on a memory chip on the main board (not the same chip that holds the VIN). There are companies that know how to program this chip, such as white auto and media. You can't program this chip yourself.Ok how do I change the program file ? Where is it.
The one for premium/non-premium IS on that small chip with the VIN. The radio I have in my car now came from a 2015 that had UQA. It sounded dead (a gap in the midrange) since I didn't have a bright speaker in my dashboard. I reflashed the radio using a file I got from my original 2013 MyLink and the sound went back to normal.The configurations are stored on a memory chip on the main board (not the same chip that holds the VIN).
There may be some tone configurations on the small chip with the VIN, but some of the configurations for the Pioneer system might also be stored in a different chip. Today I plugged in another MyLink radio I had picked up from a 2013 Cruze without the Pioneer system (UZ6 not UQA). I had the same problem that @cmarkwart is having. No audio at all. I plugged the radio back in that came from a known Pioneer system, and audio was good.The one for premium/non-premium IS on that small chip with the VIN.

I'd imagine that a radio configured for UZ6 installed in a UQA car would lean toward a pronounced mid-range sounding like a 5-transistor AM radio with a 2" speaker.
Probably not sending the signal needed to turn on or unmute the amp. Did you try copying the contents of the chip from the UQA amp to the UZ6 amp and then plugging it into a UQA system?I am not sure why this happens, but plugging a MyLink from a car that didn't have Pioneer into a car that does have Pioneer produces no audio.
Yes, I tried copying the content of the chip. No luck. @cmarkwart tried it also (I sent him a copy of the contents of the chip from my radio that came from a car with Pioneer).Probably not sending the signal needed to turn on or unmute the amp.

While it's possible, I have my doubts that the bigger chip is different for the same model year run. The reason is, it take time to flash the bigger chip. So either they'd have to be pre-flashed and tracked so the right one gets to the right car (yes, that happens for a lot of things - but still a pain), or everything needed for the year is in the big rom and the car-to-car details are flashed into the small chip as part of waking up the car for the first time. Seems to me the engineers are paid the big bucks to simplify and streamline the production line - not to make things easy for the programmers.
Were you able to figure this out? I'm having the same issue. My old radio on my 2012 Cruze Eco has UEW and worked with the Pioneer amp. I got a new (used) radio from a 2013 Cruze LTZ with RPO codes UHQ UP9 and UWG. Installed it, all the graphics seem to work, but there's no sound at all.Yes, I tried copying the content of the chip.

I can't claim that I know anything about how they program or manufacture the radios. The only thing I can say right now is that we now have two instances where a MyLink from a non-Pioneer car did not work in a Pioneer car. Currently, I have no idea if there is an easy fix for this.
If you have the Pioneer option, then you need to find a radio that came out of a car with the Pioneer option. Installing a non-Pioneer radio in a Pioneer car will result in no sound. There are no codes on the radio that tell you if the car had the Pioneer option because there are no hardware differences in the radios. The Pioneer option was programmed into the software after the radio was installed in the car. There are two easy ways to tell if it came out of a car with Pioneer. One is to get the VIN number and go to a parts website that lets you lookup parts by VIN number. If the VIN number lookup lists the center dash speaker or the amplifier then it was a car with Pioneer. The other way is to look at pictures of the car. If it had a sunroof or a center speaker on the dash then it had the Pioneer option. Be careful with 2016 1st gen cars. In that year, some of the non-Pioneer cars had the grill for the center speaker, but no center speaker or Pioneer option. A third way is to look at the sticker in the glove box for RPO code UQA. Good luck.Were you able to figure this out? I'm having the same issue. My old radio on my 2012 Cruze Eco has UEW and worked with the Pioneer amp.
