Service bulletin M1370A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

SERVICE BULLETIN M1370A: DEALER GLOBAL POSITIONING SYSTEM (GPS) INFORMATION VERIFICATION. PURPOSE: Revision. This bulletin is to outline the Dealer Locator update that is available for GTS and GT radio navigation systems. The factory navigation system on both radios contains data and information on Harley-Davidson dealers. Just like the map navigation data, that data is not updated on its own. This is in-case a dealer changes its name, location or contact information. The free dealer locator update available to customers and dealers can update Harley-Davidson dealer information on any GT or GTS radio.
