How to get TSB software update?
 

Just acquired a 2015 Tech SH-AWD, noticed GRUNT and BUZZ leaving garage or parking lot. The noise fits exactly what this TSB describes; http://www.urvi.net/forumfiles/SB/B14-045.PDF
Is visiting local Acura dealer the only way, or NAVI update would also do the software update as well? Either way it's going to cost me, but I had bad experience with local Las Vegas dealers, avoid them as much as possible. Thanks for your help.

Navi update has nothing to do with the EPS controller and associated noises. You need to go to the dealer for this one.

Thanks!
