Hallo,
ein schwerer Bug macht zur Zeit den Nüvis der 7er Serie zu schaffen, es erscheint ein angeblicher Firmware-Update, das Gerät macht einen Reboot und findet keine Sat mehr oder lässt sich gar nicht mehr anschalten:
ZitatNOTE BY GPSPASSION 20090623 - 7.15 AM PST : Late last night we started getting reports in the forums that Garmin nuvi 765 systems were failing (and now 755s too). The scenario being : a pop-up saying a GPS update was being rolled out and then the nuvi powering off and refusing to power on again !
It is not known at this point what might be causing this, but the recent and temporary failure of the Omnitech GPS and acknowledgment by Rockwell Collins that there is a bug in some GPS receivers they built that would cause a date problem after June 20th 2009, could indicate that a scheduled fix for the 765's MTK GPS Chipset went wrong...Garmin are asking people to RMA their dead units so there is apparently no easy fix, but in case you own a 765 that hasn't gone bad, you can try renaming the GPS update files as this has spared SergZak's 765 it seems
All was fine with my 765T until today. While driving home from work all of a sudden I get a pop up about some GPS update. For the next five minutes the display alternates between acquiring satellites and GPS update. I thought cool another update. Then the Nuvi just died. I cannot power it on anymore either in the mount or from my PC. Well long story short I called tech support and got an RMA. Bummer
