harveje Posted June 27, 2014 Report Share Posted June 27, 2014 Good morning, Been trolling and reading but have a few ?? New to me 04 avalanche with an X920bt 1. no additional menu options--all greyed out --I'm assuming something do do with lockout or bypass--plan to pull unit to look at wires and if needed do the yellow/blk wire swap 2. iphone 5 pandora issue-truck has a usb cord and a 3.5mm jack- when hooked up with lightning usb cable i see pandora on the HU screen, the song name and track time is running but no sound. 3. brightness--nav map brightness is a killer at night--- will check the illum wire when I pull out but is there an adjustment? 4. wiring diagram for an 04 av-- where is the best place to find one? It's been way to many years since I've messed with these, last one was when supertuner just came out----many moons ago. Again, Thanks for the help Quote Link to post Share on other sites
harveje Posted June 30, 2014 Author Report Share Posted June 30, 2014 OK, after hrs of dicking with this unit moved the yellow/black mute wire over one space and icons un-grayed, the green brake wire looks to be on a 12+v line, will check with meter iphone 5 pandora still will not play with HU icon, I can see the song and the counter is running but no sound brightness------hold mode for a few seconds and a menu pops up---yea I checked the info and it's at version 5.0--is this the correct version for an x920bt? how does the app interface work? Thanks for the help Quote Link to post Share on other sites
Saab Driver Posted February 28, 2015 Report Share Posted February 28, 2015 Got the same issues. Just upgraded from iPhone 4S to 6. HU rejects audio completely via the Lightning to USB wire. Quote Link to post Share on other sites
