G37, Garmin The G37 and Garmin emerged strong. Both made quick work of the first leg, which took us from our Chicago offices to U.S. Cellular Field — downtown to the Dan Ryan Expressway, exiting near 35th Street, turning right to the stadium. The 3 Series and TSX struggled: The TSX’s navigation system couldn’t locate the stadium’s address (333 W. 35th St.), and the 3 Series needed its ZIP code. We procured the destination from a smart phone, thus satisfying the BMW, and found it in the TSX under the point-of-interest finder. But the Bimmer’s problems weren’t over. Stymied by the loops of the downtown parking garage, the BMW took us on a six-block parade of right turns before finally tracking down a highway on-ramp. Arriving southbound at 35th St., BMW’s female navigation voice instructed a left turn. The Sox played, in fact, on the right.
