XC90 Stereo will not turn on after dead battery
Hi and thanks in advance...
XC90 2006 T6. Has not been run for a few months (due other expensive issue) and battery had died. Jump started with no issues and ran to hopefully charge the battery. During this time tried turning the stereo on but it only lights up with initial display for about two seconds and goes out.
The right side functions (bass,treble,fade etc) all work as does the CD stacker.
Would appreciate any thoughts or solutions. Oh, and no it does not require a code.
Update....Problem solved, but I am none the wiser why. I was trying to activate the stereo after the car was started. Today I tried while key set to accessories. Stereo came to life and had not lost any presets.
