Well BMW does indeed have a fix. I had my dealer upgrade my software to Ver 25.3 about 2 weeks back and ended up without Real Time Traffic Info updates.
Well today, received a call from my service advisor who informed me that someone from BMW was at the dealer to address a Nav situation they were having with a 3 series. Apparently this person had a laptop with a software update that resolves the RTTI issue. My advisor requested that if I were within 15 to 20 minutes of the dealership to swing by as he would keep the gent there long enough to flash my X5.
I am happy to report that it worked!

I did not get to meet this BMW person but my Real time traffic updates now works. I am still checking to see if any new bugs exist but so far both traffic messsages and icons are now displayed.
The "+" sign is now gone but the "TI" letters remain.
By the way, if you are in the Michigan Area, Erhard BMW in Farmington Hills rocks!.
