Hi all,

Can anyone knowledgeable enough about gm vehicles tell is SLE -1 upgradable at all to factory navigation. Beside obvious:dash trim, lcd screen, antenna and unit itself what else would need to be added?
No definite answer that i could find. One guy from this forum was pretty certain it can be done but he never posted his result did he get it working or not. If somebody know the answer or just to point me at right direction would be great.

I would recommend contacting your local dealer for more information. They should be able to let you know what exactly would be necessary to accomplish this and whether or not it is even possible. Please feel free to keep me posted. Thank you in advance.
