Car GPS Navi Shopping
TomTom lineup
Obfuscated Marketing Buzzwords (OMB’s) abound in this segment… it’s taken me many GC’s (Google Clicks) to distill what is sold down to differentiable features.
As always Wikipedia is our friend.
Euro vs US product availability – if you sit on the Car Navigation product page and flip back and forth between the various locales (very bottom of all pages), you start getting a feel for what’s available where… DE has the “Via 125” listed right now, where GB has the “Via 120 Live” and the US doesn’t even list the Via line at all.
“GO” product line – the main difference I see here between the X/XL products is that GO includes microSD card slot and the prices are significantly higher for otherwise equivalent model/features.
“IQ Routes” – application of historically collected consumer based traffic data to your current route (TomTom.com IQ Routes home page). This data is collected from all of us by uploading via USB connection to the “Home” application on our PC’s. This data represents driving speed per road segment per time of day in order to be most accurate.
“HD Traffic” – analytical combination of mobile phone generated traffic data in addition to traditional government traffic data sources. Highly detailed white paper (from HD Traffic home page). Delivered every 3 minutes to capable devices via Live services (see below).
“Via” – appears to be the latest model line sporting most of TomTom’s contemporary functionalities combined (e.g. 5” screen, voice control, Bluetooth-hands free calling, Live Services, 4GB internal flash mem, etc, but notably NO SD slot)
“Live Services” – wireless updates via integrated cell/SIM (includes HD Traffic, etc). Delivered every 3 minutes. Requires a subscription (estimated $10/montly, even though some come with 12 months for free, any subscription like this is a big personal turnoff).
“RDS-TMC Traffic” – live traffic data delivery via radio receiver (product link). I have confirmed directly with TomTom customer support that the RDS-TMC receiver is indeed included in the box on XXL 540T and XXL 540TM models via the car charger cable. And that it does provide lifetime traffic information.
Memory – XXL 540TM World Traveler Edition (WTE) appears to be the only XXL 540 model one that comes with 4GB mem. Although other models are listed on TomTom.com with 4GB, it has been confirmed by buyers that all other XXL 540 models are 2GB only as recent as Nov 2010 (best reference, also see the main thread).
Great hands on comparison between Garmin Nuvi 1490T and TomTom XXL 540S
