This looks like it is similar to the 04 cable which I used. The GMOS cables are tried and true, not sure about this nor why ir would not work. The site I looked at did not show the sky or solstice as a compatible vehicle but should wrok same as cobalt and malibu.
I do have a nearly new GMOS-LAN-04 cable if you are interested.
Best Buy uses the Scosche product on these installs,cost of their cable is around $100.00 Amazon has this cable for $52.91,Best Buy will match that cost so what the hell sav around $50.00 on the cost of the cable.Also Best Buy will do all the wiring interface and head unit install for $125.00 kinda of thinking of letting them do that ,they want an additional $60. for the steering wheel interface install.Not sure but it may not be a bad idea to let them do that ,kinda want to do this myself.My luck something will happen when I do the install ,like a cable issue or the interface is dead in the box and I will still be without a radio.I will remove all the plastic dash so as to not have any hidden damage.
install is simple once the dash is apart. If you can remove the current radio, the rest is simple. Best buy has a great return policy. All the wiring is done outside the car, match the colored wires...i did mine in the house. Then its plug and play.
