TomTom's latest GO GPS navigation devices - the 510, 5100 and 6100 (pictured above) - include free map updates for the lifetime of the device. Maps for other countries can be installed and updated at no additional cost.
All three models have 8GB of storage, but if more room is needed for extra maps that can be augmented with a microSD card.
The lifetime updates also applies to speed camera locations and live traffic information.
The new devices also include advanced lane guidance, voice control, 3D maps, and a quick search function. 'Drive Home' and 'Drive to Work' routes are available at the touch of an on-screen button.
The MyDrive and live traffic capabilities are enabled by a built-in mobile connection on the 5100 and 6100 (data - including roaming charges - is included in the purchase price). The 510 links to a smartphone in order to connect to the internet.
The 5in 510 costs $279, the 5in 5100 is $349, and the 6in 6100 costs $399.
"With the addition of lifetime world maps and lifetime speed cameras to our new TomTom GO devices, we're offering the most comprehensive package to drivers that we've ever launched," said TomTom APAC consumer senior marketing manager Winnie Kwan.
"Our aim is to help drivers avoid traffic jams, and getting to your destination faster."
Earlier this month the company announced TomTom GO Mobile, a free navigation app for Android. It can be used for up to 75km a month at no charge, and upgrading to an unlimited kilometre subscription via in-app purchase costs $25.99 for one year or $56.99 for three years.
This replaces the TomTom Navigation app, which will stop being supported or updated on 1 October 2015, although traffic and speed camera subscriptions will be honoured until they expiire. Users of the old app can get a three-year unlimited navigation subscription to TomTom GO for 99c.
TomTom GO Mobile includes several of the features of the dedicated GO units, including lifetime world maps (stored on the device) and traffic information.
