Have had zero issues since purchase in July and now 6k miles until today. Started up this morning and both nav and radio didn't work.....got message "not available". After about 10 minutes, went into Home Depot for about 15 minutes.....started back up and both were working again. Googled the issue when I returned home and saw posts about keys and battery disconnect.....mostly on older models. Appreciate any feedback regarding a potential issue here?
