Just to add my 2cents, in general for the GM system to work, there also has to be lines on the road, if there are none then the system does not work, if covered in snow, again the system will not work, it does not mean that its defective, but it is reliant on outside factors. GM knows this and has been adding the gen 2 system to Cadillacs, this uses the Sat network and can place you anywhere on the road. I expect in the next 10 years almost all GM vehicles will have it or have the option for it.
