nav in 08 denali sux

[roblau004]

Just took a 1100 km trip in home province of Alberta. Good thing I knew where I was going , cuz for sure the factory nav sys in this unit would have got me lost and stranded. Instead of taking major highways , it suggested that I take secondary roads , and would not "recalculate". It only started to work properly on the return about 3 km from home. Gotta stay with suction cup Garmin , allot more dependable. The GM nav cant even rate a "poor"

Imagree and i have a 2010. Absolutely worthless. My moms $100, 3 year old 3" garmin is better.
Illprob never get another nav in a vehicle bc the after market ones are so much better
