Several times over the past few months (well over a dozen instances), I've been driving along in my 2003 Mazda Miata and my 2nd generation Automatic has chirped and my speedometer dropped to zero. This lasts 30-90 seconds and then Automatic chirps again and the speedometer comes back to life. During these periods the odometer also apparently stops recording. Occasionally this has happened 2 or 3 times in the course of 5-10 minutes. The speedometer has never failed to come back but I'm wondering if this is just a brief firmware update interruption or symptom of something more serious that needs attention.
