fdkile Posted May 2, 2016 Posted May 2, 2016 Hey Folks, New guy checking in from Wisconsin. I recently traded my 2003 Avalanche for a Sierra crew cab and found this site looking for some upgrades to my navigation and the suspension. If anyone has some suspension tips, feel free to share. I am looking at sway bars and different shocks, while maintaining the stock ride height. I will probably be getting the HMI module to get my nav upgraded after reading through the really long topic on upgrading the Intellilink/Mylink. It seems like it works well and everyone is happy with it. later...
