I brought in my 2008 Toytoa Tundra for a new radio head unit. Sean was extremely professional and helped me pick out a Kenwood unit with built in GPS. He even installed a front and rear camera set up which makes parking my truck so much easier. The best part is how dependable this new head unit is. Several months later, and I have no issues with it. I'll definitely be back in the future for more upgrades.
