The TomTom for iPhone app has received an update on Wednesday bringing with it a number of promised features and a couple of new ones too.

New to the mix is compatibility for the original iPhone and iPod touch (all models), meaning that owners of the iPod touch, with the help of the TomTom Car Kit can get in on the TomTom for iPhone GPS action too.

Aside from that, features are as expected so that means advanced lane guidance for difficult junctions in both landscape and portrait mode, and text-to-speech functionality that will see street names and places read aloud as part of the spoken instructions.

In addition, TomTom's "Help Me" emergency feature from its in-car satnavs will be ported to the mobile platform, there'll be options to customise audio warnings, while maps and safety camera databases will see an update.

Finally the app will catch up with other offerings like CoPilot on the market by adding iPod player control "ensuring drivers can conveniently control their music from within the application".

The update is free to all those who have already downloaded the application.
