TomTom ONE 140

The TomTom ONE 140 IQ Routes edition is the latest entry-level portable car GPS navigation unit from leading manufacturer TomTom. I’ve never owned a GPS navigation unit before but, having seen some of my friends’ GPS navigators in action, recently decided to take the plunge with the TomTom ONE 140 (using some of my K-Rudd stimulus money). Here are some of my thoughts…

Firstly, TomTom’s patented EasyPort mount is fantastic! The suction cup attaches securely to the windscreen with a 30° twist of the knob (and releases with the corresponding anticlockwise twist). The TomTom ONE then clips into the adjustable ring – simple! It’s quite a light and compact unit (especially when detached from the EasyPort mount) and I carry mine around in a Crumpler Thirsty Al (large) pouch.

The user interface on the device itself is user-friendly and intuitive. It’s displayed on an excellent 8.5 cm LCD touchscreen which offers a wide viewing angle and decent visibility in sunlight. Surprisingly, readability is unaffected by polarising sunglasses – I haven’t come across an LCD display with this property before.

Text-to-speech (TTS) is standard on the Australian model and in most other regions (it’s optional in North America, where the TTS model is designated ‘ONE 140•S’. Whilst undoubtedly useful (when roads are clearly signposted), the voice synthesiser struggles with uncommon and non-English names… although curiously, it pronounces ‘Parramatta’ quite well. It should be noted that TTS only works for ‘computer’ voices, of which there are only four English-speaking choices (female UK, male UK, female US, male US). I also recommend disabling ‘read aloud road numbers’, since the UK-oriented TTS will irritatingly spell out State Routes and Metroads, for example ‘S-T-A-T-E route thirty-one’ and ‘M-E-T-R-O-A-D four’ – disabling this feature results in the TTS announcing the actual road name or road sign instead.

I’ve been using it a fair bit over the past few weeks (covering a range of trips mainly in/between the city, inner west, and north west). The Australia map uses Whereis map data from Sensis, which has proven to be reliable so far. It generally does quite a reasonable job of plotting routes, although it does occasionally suggest impractical turns (e.g. unsignalled right turns onto a major arterial). The algorithm also tends to prefer major roads, in spite of the IQ Routes feature which is designed to calculate the fastest routes based on collated user data. Probably the best way to summarise this is that it might not necessarily get you somewhere the best possible way, but it does get you there.

GPS positioning is usually accurate to within 5–20 metres and the unit can acquire an accurate GPS position within 5–10 seconds when QuickGPSfix is up-to-date (signal acquisition can take over 30 seconds otherwise). Like other GPS navigation units, however, navigation can be patchy in certain situations: areas where tall buildings block line-of-sight reception from GPS satellites (e.g. Sydney CBD), on densely arranged and/or vertically stacked carriageways (e.g. Western Distributor Freeway), and where carriageways change direction during the morning/afternoon peak (e.g. Waringah Freeway).

USB connectivity allows the TomTom ONE to be managed using the TomTom HOME software package, including updates (Map Share, QuickGPSfix, etc), downloads, backups, etc. In addition to the Windows version, TomTom HOME is available as a universal binary for Mac OS X.

Overall, I find the TomTom ONE 140 IQ Routes edition to be a well-designed, user friendly, feature-rich entry level GPS navigation unit.

  1. GPSes are awesome, although sometimes they take you on a strange route… but at least you know somehow you will get there, yes.

    Dunno about brands of GPSes… they should be all similar, right?

  2. Now that you’ve reviewed TomTom, can you review KenKen please? 😉 Sorry I’m just bored and having a brain freeze in between editing paragraphs…

    Apparently TomTom and Navman are the market leaders in Australia (though TomTom is bigger internationally). I imagine that navigation would be mostly similar between brands, considering they all use either Whereis or Navteq maps anyway (in Australia). The main differentiators are things like EasyPort, TTS, Map Share, etc.

    @Lamb
    You MUST be bored. =) And I have no idea why they named their company after a type of drum…

  4. KenKen is the name of a game similar to Sudoku. I think its in the SMH. Its not made up so you CAN review it… :p

    Using TomTom as a name for a direction device makes sense… I guess the sound that the drum makes (and hence how loud you can hear it as you go closer) is similar to someone saying warm, hot, hotter, etc to alert someone they are getting close to something? hehe

  5. Hm… I never got into スードク, so I’m not sure about ケンケン. Regarding the drums analogy, it actually turns out that you’re not far off the mark…

    ‘Anthropologists claim that drums mark the start of communication technology. Signals and messages were communicated over great distances with drum beats to ensure travelers would find their destination as quickly and accurately as possible. Exactly as TomTom does today.’
