Equinox keyless remote start short range

Hey guys hoping someone can help me. I want to extend the range of the remote start in my 2008 Equinox sport. I read on the forum here were someone did it with a tahoe. The problem I have is were is the antennae? Any one out there that has had the same problem with short range of keyless entry and remote start let me know.

I have a short range remote start problem with my 2008 Silverado. Does anyone have a fix for this?

GM's remote start system is great, but has a couple flaws. the run time that is not adjustable, and the range of the remote. Because the system uses the keyless entry module, it is limited in range.  There are aftemarket modules that use an external antenna and replacement remote that activates the factory remote start.

Do you have an address of the people that have this after market module?
