Speedo correction - information please

Comparing my '05 speedo reading to my GPS, at an indicated 120 kph on the speedo the GPS shows 110 kph. I've heard that this has been intentionally done by BMW. Is there a fix to bring the speedo back to correct readout ? I think I read somewhere about a jumper on a circuit board ??

Addendum: I'm not sure if this fix applies to the 2005 model. Others will chime in and clarify that issue.

Here's what I did on my 2000 and here's how I found the method again:
Clicked on "Technical" on the link bar at the top of this page,
Clicked on FAQ (frequently asked questions),
Scrolled down and click on "Common issues",
The third line down is "•My speedometer is way off. Is there any way to fix it?",
Clicking on that link will take you here:

http://www.bmwlt.com/forums/faq.php?...0lt_faq_speedo

Links imbedded on that page will take you to a description and pictures of how to do the job.

Lots of other great info in the FAQ and Hall of Wisdom sections contributed by many folks on this site over the years. Great resource, huh?
Have fun.

Like Curtis, I wuzn't sure the speedo mod listed on the forums for '99 to '04 model years applies to the '05 and newer models. After checking, I see that it does NOT. Under the "Similar Threads" box below this thread, take a run thru the various posts in the "Speedo Error Correction for '06 LTs". You'll find a sure fire fix posted by Mark Neblett that seems to be the most reasonable and prolly easiest to do. Good luck.

Re: Speedo correction - information please

BTW, I forgot to mention the following. In addition to navigating thru the HoW forum and the FAQ list like Curtis aptly described, to find the speedo mod, there is one other avenue. For those with '99 - '04 model year LTs, who might be looking for the archived info, you can use the Home Page here and drill down thru the "Featured Articles" box (lower most box in the left column line up of the page) to find the speedo mod article.

BTW #2 - think about editing your thread's subject line to include the year model of your LT. That way, folks looking for the speedo mod for '06 LTs will maybe benefit from reading your thread in their search for info; AND folks looking for the mod as applied to '99 - '04 won't have to wade thru all the info regarding '06 and newer model years. (Hmmmm - not sure I made that clear; more coffee please!!! ).

Yep Dick, clear as mud, thanks. I'll try harder in future, nothing like helping the data base out for future searches. Thanks for the tips, Dennis.

Re: Speedo correction - information please

The only way to mod the 05 and up speedo is to take the unit apart and pull the needle off and replace it back on below 0. There is no nice jumper like the early bikes. 3.33 mph per tick mark, what was BMW thinking on this design? I just use the GPS.

+1. This is also my solution. Works like a charm. I seldom look at the speedometer as the GPS is about as easy to see and much easier to read than the BMW speedometer with the nonsensical tick marks. Obviously, the person who designed the silkscreen for this speedometer did so after a few too many beersteins full.
