    Did you check the fuse panel in the engine compartment? On the lid of the fuse box it should have a diagram and label for each fuse.

    Hmmm...how about the fuse panel on the inside of the suburban? It's underneath the dash on the drivers side on the left.

    Thanks, i found it (in the eng. compartment) and i will tell you why i needed it. on my way to work yesterday, My Edge CS was working fine. When i got on the Hi-way, i looked at the monitor and it was not working. i messed with all the buttons but still nothing. when i got home, i called edge tech support. they told me it was a power/ fuse issue. when i finally found the fuse, it looked fine. i pulled it out then re-inserted it and the buttons on the Edge lit up but the screen was still black. Tech support had already gone home so ileft a voice mail. Bright and early this morn. They called me back. i described the issue and they told me they have had some screens go black due to an issue in the monitor which they now know about. they will repair it free of charge and it only takes 1 day turn around. i can tell you that Edge support will not blow you off and promptly return calls and emails.
