For those folks who have no sense of direction, an on-board navigation system provides assistance in finding your way.
The 2008-2009 Suzuki SX4’s navigation unit lid may make a grinding noise when opening or closing. The cause is a vibrating pivot spring on the pivot shaft.
Suzuki recommends the application of a small amount of grease with a small brush to the spring pivot shaft. Suzuki recommends the use of Permatex P/N 81946 Ultra Slick paste lubricant, or equivalent multi-purpose synthetic lubricant.
