Copilot

SAT-NAVAPP

IF you can’t stretch to a standalone sat-nav, a smartphone app is the way to go in winter. Co-pilot was the Best Buy in our Issue 1,493 test, as it’s easy to use, the fastest to plan a route and offers several options to avoid jams. Although some apps were cheaper (and some were free!), we reckon the accuracy, clear alerts and general performance make Co-pilot a worthwhile investment.
