I replaced my dead radio with one I purchased from one of our members; was excited when I finally got to the point of plugging it all in and testing it - the power is coming on, the screen is reading functions (radio, tuning, CD, etc.), but I have no sound at all! :confused: :(

I did the reset thing with the battery, but still no sound. I rechecked all connections, they all seem solid (pics attached). There is a connector that I don't have a mate for (last pic); by now, I'm not sure if it every had one, or is just a connector for something I don't have.

Your knowledge is much appreciated!

Try pressing the "note" button and see if the speakers are turned off. Keep pressing it until "spkr" shows up and the hit the left or right arrows on the handle bar control to change the setting.

Rudy,
Sorry about the problem. I did have an intercom system and mostly rode with the Speakers Off. I am glad that you got it working that easily.

Well, I got everything together, rolled her out of the garage, went to start her up, and...nothing! Battery dead! Hadn't had a problem up till now with the battery. The dealer said that the radio unit had a short, and if I replaced it, it would be fine, but now it seems there's a short between the radio and the battery! This SUCKS! Any ideas where to go next?

Ok here is another tip. There is a documented issue with using radios with one version of firmware and controllers with an earlier version - excessive current drain with the bike off. Next time before you shut off the bike, turn the radio off with the controller button, then turn off the bike.

Here are the notes on that:
To test your '99-'04 Radio/Radio Control Unit (RCU) (radio displayscreen in the stingray) for the software version each is running, do thefollowing:

NOTE: The '05 and '06 K1200LT Radios/RCUs with the radio display in theinstrument cluster are slightly different.

Turn on the radio and within 8 seconds push and hold down the "MAN"button on the stingray radio control panel. You'll see "SVOL" appearon the radio screen (controls your speed volume/rate of change and isadjustable from 1 to 4). Continue to hold down on the "MAN" buttonuntil you get an 8 character radio serial number displayed on the screen. Nowrelease the "MAN" button.

Next, press and release the radio "SEEK" control on the handlebar.You should now see the radio software version (on the radio screen) that willlook something like SV 0300, SV 0400, etc, up to SV 0700 meaning that the radiosoftware version is 3.0, 4.0, etc.

To get the RCU software version press the "MAN" button again and youshould see either BID 2.0 or BID 3.0.

NOTE: Here's where I've found the '05/'06 models to be different and I haven'tspent enough time with the various buttons to figure out how to get to the RCUversion on these bikes.

If you have a RCU with version 2.0, it will work with any radio softwareversion, and they are: 3.0, 4.0, 5.0, 6.0 and 7.0 respectively. If you have aRCU with version 3.0, you WILL get the battery drain problem if you do not havea radio with version 7.0 software. In order to keep the battery fromdischarging with a RCU version 3.0 and any other radio software version except7.0 you must use a Battery Tender or some reasonable substitute, or religiously1)turn off the radio first, and then 2)turn the key to the fork lockingposition each time you park the bike for any extended period.

NOTE: There is no way to update the radio or RCU software that I'm aware of.You've got what you've got. BMW did acknowledge the battery drain problems withthe software mismatches and either changed out Radios or RCUs to eliminate theproblem in the affected customer's machines. Becker, the K1200LT radio supplierthen subsequently started producing radios with software (Ver 7.0) that wouldwork with either version 2.0 or 3.0 RCU software.

John, radio software version is SV 0700, RCU version is BID 4.0; how does this fit into the two categories? Also, I charged it overnight, so it now has a full charge; I tried starting it, and it's turning, but not starting. So, will a possible short in the radio unit keep it from starting up? Or, do I have another problem?

Before finalizing the radio install (everything off the fuel tank) I was starting the bike no problem. I also plugged the radio in to test it; changed the speakers to on, and everything still was good. It wasn't until I put the stingray back in and all the plastic back on, that it wouldn't start - completely dead. Can this radio problem kill the battery that fast? Or, should I be testing my electronic ignition, or something else? :confused:

Rudy,
I never had a problem of the radio draining the battery. I almost alway rode with the radio on and hardly ever shut it off when I parked the bike. That said, I rode nearly every day, but even the few times of sitting 7-10 days, it always started. Could the battery be weak and ready to go anyway? I think I would charge it up and see if someone could test it.

Hey Lowell, I actually charged it overnight, tried starting it, but all it did was turn, never started - my bike usually starts very quickly. Now, I'm wondering if it's something other than the radio draining the battery - ignition, starter...? But, before installing the radio/stingray, I was starting it up no problem, so just a little confused now. I don't want to have to take it all apart again, but looks like I may have to.

Did you unplug the fuel pump while you were in there? Do you hear it charge up for a couple seconds when the ignition is switched on? Checked your engine kill switch? Checked your reverse lever?
Yes, unplugged the fuel pump, changed the filter and 2 hoses connected to the pump. I do hear it charge. Reverse lever is in forward. The crazy thing is once I got the fuel tank back on it was starting fine, like normal! Plugged the radio in and mounted the stingray; put all the plastic back on; set the seats and no starty! Dead as a door nail.

Did you disconnect any wires from the battery, did you reconnect all the wires to the battery ?
I disconnected all wires, pos and neg, and pulled the battery while I did all servicing. I've searched to see if I left any off - they're all there. I'll most likely be pulling the plastic again, so I can get a better view of what might be going on! Ughhhh! :crybaby:

Rudy,
I am stumped too. How is the speed cranking? If it seems the bit slower, I would still test the battery. If there is another LT owner nearby, can you borrow his battery to test?

Just an FYI on the battery. It must be at full charge to get the LT to crank over. I've jumped a few that were weak and the bike fired up. Even charging over night will not fix a bad cell.

All you need to check the battery is a set of jumper cables. Just jump start it from your car. It will not harm the battery or electrical system if connected in the proper (plus to plus & neg to neg) fashion.

Sounds like you are OK on the radio. Retrace your steps - it was working fine before you hooked up the radio. Was there anything you undid as you hooked up the radio? If you undid the battery in that period you may be missing one of the wires on the positive terminal. There should be two 6mm red, one 4mm red and a 10mm black/yellow with a red sleeve. All on the positive terminal. Not counting any aftermarket stuff.

Lowell, the cranking speed seems to be fine.

Dan and Dean, I just tried jumping it - had full cranking speed and still wouldn't start up! The plus side is, I found my heavy duty jumper cables that I thought I lent out over a year ago! :)

If it's still not starting, what are my options? I'm thinking I need to get back into the fuel tank and check the pump, filter, hoses and connections - shoot!

Found the problem - Dohhhhhh!!! I think I do qualify as a journeyman tupperware remover/installer though!

Thanks everyone for all your input - I'll have her rolling this afternoon!
