Radio Malfunction: 2003 K1200LT

[Dogg]

I left the key in the "R" position on my 2003 K1200LT with the radio on (I know... nice move stupid!)

The bike sat for a full week and drained the battery... Voltage was so low that the indicator lamps on the dash would not even glow... I have never seen that dead of a battery on any vehicle before. It behaved as if there were NO battery in the bike at all!

I quick charged the battery (40 amp setting) today for 20 minutes and the bike started and runs fine.

But... now the Radio/CD/CD-Changer DOES NOT function at all!!

The yellow "back light" comes on when you turn the key on, but it no longer says "BMW" for 3 seconds and the LCD digits flash on for a split second and then fade awayl. I have disconnected the battery ground cable and removed the radio fuse several times to see if the thing will somehow "reset", no luck!

My dealer says there is no radio theft "code" for this model, as does the owners manual for the stereo. Yet, I recieved a small credit card with the bike that says it is a "RADIO PASS BMW", that has a bunch of letters and numbers on it!

My dealer is a long distance from my home. I hate to wait for an appointment, and waste a ton of time to find out that there is a code or some simple "reset" function that will suffice!

Questions:

Did I do something wrong when charging the battery?

Is there an internal battery in the radio (for saving radio station presets) that may have been drained so much that the radio has lost it's mind? This happened once to me on an old Pioneer AM/FM Cassette player.

What the heck is this "RADIO PASS BMW" card?

Any help would be greatly appreciated!

In the end, the issue was not the radio, but the "remote control" unit that communicates with the radio.

It must have been defective, even though it operated fine, and when the battery ran down, the low voltage caused it to die...

I hope that it is not a design flaw that will fail again (should I manage to run the battery run down again)

Thank goodness for the warrantee..!!

BTW, the BMW Radio Pass is useless as there is no security code.

I guess that this little problem is just another example of what can happen on these (hi-tech dealer only repairable) bikes. Hope you don't go thru the ABS problems that I have just been through. I'm still waiting on my reimbursement money from BMW roadside assistance.
