Factory Navigation issues
 

My shop has been trying to figure out an electrical issue of constant draining that has been happening on my car. They think it’s the viper alarm system. They are now telling me of a new issue of the navigation randomly blipping and the windows rolling down and the abs light coming on. They can’t get everything to replicate all the time. Has anyone had any issues close to this? 2009 navigation by the way.

Put an ammmeter on the battery and start pulling fuses - when you get to the fuse supplying the drain, the current will drop.

I have an '09 with navi and noticed twice within the last year my windows were rolled down for no apparent reason. I thought "Great... this is defiantly going to happen again while parked in the rain..."

My initial assumption was that buttons were getting pressed on the fob in my pocket and triggering the roll down, but that seemed like a long shot as its a multi button procedure. If its Navi related.... ugh. More reason to replace it with aftermarket!!!
