If you are not planning to buy a Nokia or have not done so already, you need a good GPS navigation app.
Navigon has just been updated to version 4.3, which brings new route planning features, and provides a full-featured, off-line navigation solution.
This does not normally come cheap, and Navigon is no exception, but the company is running a sale at present.
Navigon Europe can be found for 59,49 Euro, down from 85,49 Euro.
Navigon USA can be had for $29,99 only, down from $49,99.
The deal expires on the 31st October.
