How reliable and ACCURATE is the OEM Telematics Navigation System (such as those found in Cadillac models)?
I am looking to purchase a vehicle with an OEM Navigation System, but want to make sure that I’m not buying an old data base. I have noticed significant differences between Nav/mapping systems. The one I have on my Verizon phone recognizes my home address, while MapQuest doesn’t, for instance. My neighborhood is at least 5 years old and should show up on both.
