I love my 07 Sienna van...but....the interior 12 volt outlets go off when the key goes off.
I know the reason ( to prevent battery run down if something is plugged in)...but...I would far rather take a chance on leaving something plugged in and running down the battery..over..having my Garmin GPS and my external XP radio go dead EVERY single time I jump out of the car for a few minutes. The battery back-up in each of those devices doesn't last long enough.
Any ideas or suggestions appreciated. I did read the manual but couldn't find any re-programming or other fix. thanks, Rich
