RonS Posted January 21, 2011 Report Share Posted January 21, 2011 Has anyone figured out why it does this from time to time, it seems to be getting worse. Thanks Do you mean why the unit restarts/reboots when cranking the starter? Don't know what else you could mean. That is because of the voltage drop due to the current draw of the starter. It is anoying, especially since the reset somehow blows away my iPod VR catalog - it takes much longer to rebuild than after a normal scenario (off, on, start before HU has initialized only takes a few seconds to update the VR catalog). I had thought about wiring in a diode and capacitor in the +12v feed to the HU to see it this copuld be avoided. But don't know how big the cap would need to be. I also wondered if it is the constant +12v or the switched +12 circuit that trips the reset. The key switch may turn off ACC while in the starter position - so all the battery current can be applied to the starter. Anybody conquered this issue? Quote Link to post Share on other sites
flash_the_hun Posted January 25, 2011 Report Share Posted January 25, 2011 I think that a cap wouldn't help much. Maybe a DC-DC converter or a small backup-battery, which gives stabilized 12V to the HU during cranking. Quote Link to post Share on other sites
Thumper88 Posted February 5, 2011 Report Share Posted February 5, 2011 I haven't experienced this problem, but a time delay relay on the red (ignition switched) wire is how I would solve this issue. Just need to delay the unit from the time the engine is turning over until it has started. Quote Link to post Share on other sites
