BrianP Posted August 17, 2009 Posted August 17, 2009 I just had my first problem with the navigation system (2007 ES350). The map/destination screens said "external system not connected" and the radio screen read "audio off" while the audio was on. When I shut the car and restarted, it appeared to be OK, but is this the beginning of a problem or just a fluke occurrence? Thanks.
SW03ES Posted August 17, 2009 Posted August 17, 2009 Probably just a fluke. Mine has had some flukey moments over the years...
UCF3 Posted May 29, 2013 Posted May 29, 2013 It might be a reoccurring issue. Just got my disconnect message from the NAV system after I was troubleshooting my VAIS XM started to give out. On some of the other forums this issue is reoccurring and nobody has a permanent fix other than replacement
