That's a great question but I don't have an answer, you may want to do a little more research to see if this is compatable with the GM nav system.
I'll give them a call or something to see if it is. Thanks for getting back.
I sent them an email on it, also found this video that may explain a little more on how it's plug and play.iSimple GateWay Overviewedit... they also have a compatibility drop down. I need the ISGM575 for my 03.
so I ordered the ISGM575, installed it today. works flawless! no problems with the factory nav. i'll grab some pictures and maybe a video of how easy working the interface is tomorrow for you guys.
