I8Hmudders,
Im a long time reader and new on the posting side. I have a 2008 200 Series with 137k miles, fairly stock with exception of a mild suspension upgrade from Dobinson. Owned it for over 10 years, 3rd or 4th cruiser, currently 1 of 2 in the family inventory.
Last week my audio & navigation system went out and is displaying "external system not connected"; however the climate control functions still work on the MFD. I have search multiple forums (both Lexus and Toyota) with the majority of the post associated with the Toyota Prius and select Lexus models. The 100 series seemed to have a similar issue as well. I did find Tim's post: Audio Issues . In our messages, his issue seems to be isolated to the amp. Not sure if the AMP also could affect the Nav functions as well?
Over the last week, I have disconnected battery to attempt a MFD reset with no success, checked/ replaced all fuses from all three panels with the Toyota low profile, pull connectors off amp to inspect and reconnected. I have not pulled the MFD unit to inspect any loose connections. Before I go down that path, thought I would see if others have advice to continue to trouble shoot in the event I missed something.
With respect to modification of the audio system, I did replaced the front pass and driver side door drivers with 2 Ohm units this past summer. I have noticed since that swap, the volume has diminished, requiring additional gain to achieve similar volume.
Thank you in advance for sharing your knowledge and insights.
