I have a 2007 legacy 2.5i, I dont have the same problem but close. As soon as it started to get cold out my cars radio would lose the presets and spit the cd out when you started the car in the morning after it sat in the cold all night, and then sometimes when you started the car the radio would just come on quick and turn back off but also lose the presets and spit the cd out. I noticed the car turns over harder but I figured it is just because it is colder. I cleaned the corrosion off from the battery posts and wires and put a little vaseline on the posts but the problem still happens. I was just wondering if maybe my cars issue is caused by the same thing causeing the radio/hvac issue.

 

 

If you are still on the original battery, it might be time for a new one. It might explain you losing your presets (not sure about the cd spitting out though). If you don't have the means to test the battery yourself, I believe the auto parts stores can test it for you.

The dealership replaced mine under warranty. Be sure to check the bezel around the shifter when they are done...because they scratched the hell out of mine during the swap. I had to come back about 2 weeks later for them to replace that piece too.

I just had this issue happen to me. About 6 weeks ago, upon ignition, both radio & HVAC displays were blank...I immediately just shutdown and restarted the car, and all was fine. Well, last night when driving home from work...I happened to notice that parts of the radio & HVAC displays looked funny....I could see thin horizontal red lines between the pixels...and some pixels were missing...and different parts of each display were dimmer than others and were flickering just slightly. So I got home...left the car on...took some pics (in case the issue magically repaired itself). I then shut the car off. Then I turned it back on....and both displays were blank. I restarted it again....and got the same result. So, I tapped the side of the console lightly with my knuckle....and the HVAC display came back on. Everything appeared to be functioning besides the display. I called the dealer, and they said I could stop by and they'd have a tech verify...and order a new unit. I also noticed a slight hum coming from the unit that wasn't there before.

Makes sense to me.. but let me rephrase your question in software terms - maybe that'll be easier:

 

Let's say a stock car comes with ECU version 1.0.

Accessport comes with a nice version 2.0.

 

You flash ecu to AP 2.0, the accessport saves the orig ecu version 1.0 to it's memory (if it does that)

 

You're about to take the car back to the dealer, you flash it back to ecu version 1.0. That version still remains in the AP as well (?)

 

Dealer takes car, flashes to a new factory 1.1 version.

 

You take the car back, now you flash it to AP 2.0. The question then becomes, which version will get saved - factory ecu 1.0 or 1.1?

 

 

You would need to unmarry the AccessPort from your current ECU....or you might not be able to use the AccessPort when you got your LGT back from the shop without jumping through hoops with Cobb Tuning. I'm pretty sure the AP doesn't "backup" your original stock map....unless they finally released a new AP version that has this capability. Rather, you use a stock map that Cobb has available for you to use.

I have seen discussions on this forum in other threads about stock maps flashing with the AccessPort. I think there was talk of your original software map from Subaru being watermarked somehow so that it reflects a serial number of your ECU. While the AccessPort can reflash back to a stock map....I don't think it can backup YOUR actual stock map so that you can reflash at a later date to exactly the way it was before. There had been talk that this capability would come out...but I'm not sure when or if it ever will. I was hoping that it would before I get my AP.

The Car & Driver article that was referred to earlier in the thread mentioned that they started the "Top Tier" certification in 2004:
