Hello, Your head unit gets reset each time the ignition is switched on because you don't have the CONSTANT yellow power wire on the radio connected to a constant power source- you have it connected to an accessory wire.
The dealer installed it wrong. The yellow "constant" power wire on the back of the radio saves all your settings and clock functions. This wire is intended to be connected either directly to the battery ( so that it never loses power) or to a constant power wire behind the dash. Instead, the way your is installed, the yellow constant wire is being switched On/Off with the ignition key. This causes it to lose settings each time the car is turned off.
There is a red wire on the back of the radio that is designed to be switched with the ignition. The dealer likely accidentally switched these two wires around. So again, to clarify: Your radio will NEVER lose settings when the key is switched on and off if:
1) The Yellow constant wire is connected to a constant wire behind the dash- or directly to the car battery.
2) The red switched wire connects to a switched ignition or accessory wire.
3) The black radio ground wire is connected to the metal chassis of the vehicle.
If red and yellow are accidentally switched, then your radio will come on when the key is turned on, but as soon as it is turned off- the yellow constant wire (which stores memory) will lose power thus resetting your radio back to default settings.

That is literally the only thing that will cause the radio to lose settings when the key is switched- it's nothing to do with the settings/adjustments. It's wiring related.
Do you need further assistance with this?
That is a completely different question than the one that was posted regarding the settings being lost when the key was turned. Per the site protocol I am not allowed to respond to that additional request. That would need to be posted as a new question, as I am only privy to the original question. With regards ***** ***** was posted, could you please click a POSITIVE RATING (3-5 stars at the top of the page) and click SUBMIT so that I am credited for working with you today?
Please rate this question positively before posting the new one.
I was just following up to see if you needed further help? The site shows that since the question is open that you are still looking for help. Or, if you received the information you were looking for-could you please kindly rate my service POSITIVELY (by clicking a 3-5 star rating by scrolling to the top of the page)? Thanks in advance.
