Radio lost it's preset stations and ejected CD at start-up
 

I started my car last night and heard the CD eject. I didn't think too much about it because I thought that I must have bumped the eject button. Then I discovered that all of the station presets have been erased just as if the battery was disconnected. I think it is strictly a problem with the radio because the clock was not affected.

Anyone had this happen? Any ideas on what might have caused it?

Just a guess but if your battery is going or was low your cranking voltage may have been too low to maintain the memory. You notice any slow cranking lately? It may be battery time soon.

That was my first thought too. But the clock wasn't affected so I ruled the battery out...but stranger things can happen. Haven't really noticed slow cranking either. By the way, the car was driven for about 40 min and sat for about 45 min right before this happened.

It's time to swap out that HU, log on to www.crutchfield.com not only are they affordable, their techs will walk you through the wholr process. It's possibly one of the best things that you'll ever do for your car.:)

Your clock take very little voltage to keep the memory of the time. As for your radio takes much more voltage to mantain the presets. It may not be your battery but maybe your alternator. Which will end up messing up your battery. Depending where you are some of the auto parts will check both the battery & alternator for free. If in the Texas area Auto Zone does that for free.

Battery tested at 575 cold crank amps. Alternator charging at 14.33. (I am fairly sure on the alternator #...it might have been 44.33)

We couldn't find what the cold crank amps are supposed to be for the battery. The guys said that 99% of all cars have a battery with about 575 cold crank...but I would like to know what it is supposed to be.

What is an HU? (based upon the link it is some kind of electronics thing, but I don't know which.

And before anyone flames me, I did a search and the ORG search engine won't let you search for words less than 3 letters long.
