Boleezy Posted October 16, 2016 Posted October 16, 2016 I purcased a 2011 GMC Sierra that has the Advent OGM 1 installed. Recently the system stopped playing. When the truck is started the screen would come on as normal but would black out for 20 seconds. The screen would come on again amd black out again. This continues the whole while the truck is running. Does anyone have troubleshooting advice?
rt66er Posted October 19, 2016 Posted October 19, 2016 Can't necessarily answer your question, but you can download the owners manual at: https://mans.io/item/Advent/OGM1 Maybe just needs to be reset/rebooted...?
