At the next junction, go downhill. Garmin tanks as Google launch free Sat Nav.

Garmin down 18%, Tom Tom down 9.5% after Google announce free live Sat Nav to mobile phones. Having just been give a quote of £3,100 + VAT and labour to replace the Sat Nav/Air Con system in my car, I take some pleasure in the knowledge that I now have an alternative. Sat Nav on my phone: £0. Plug-in ceramic car heater from Amazon: £17.97. Making £3,500 while someone else loses about a $billion: weird.
