Hello all, Ok so I've had my first bug pop up. ive had my 600 for a few weeks now. been testing it between the car and my 690e upgraded from v4.2 to 4.5 and now ive lost 90% of my street names. My map shows all the streets but wont show the names any longer. I have CN2010 loaded on a 32g card. I took card out while i did upgrade. Ive deleted and reloaded map on card just in case something was corrupted. tried changing the detail level on the 600 with no luck. master reset no luck. I thought i read in this post that a similar event happened to an inmate but now i cant find it..... any suggestions? I also took out the card and tried it in my other garmin devises and they all work fine (60csx & 705). any ideas ???
