Garmin Nuvi 200W Portable Navigation Device Teardown

15 April 2008
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Main Features / Overview

Though it features the wide screen, the Garmin Nuvi 200W is only just a little above the Nuvi 200. From a hardware perspective, there are some internal structural differences as well - but both the 200 and 200W represent the lower end of the Garmin line. With the exception of the 4.3 inch diagonal display, view this device has only the most basic features - a screen and a speaker - as do competing low-end units (no Bluetooth, no FM transmission, no TMC, etc.). In fact, no matter who the manufacturer is, the 'basic' models lack most of the following features which are reserved for various flavors of high-end models: Bluetooth, FM transmitter, and RDS-TMC receiver (for real-time traffic conditions).

The Garmin Nuvi 200W features including a 4.3 touch-screen 16M Color 480 x 272 TFT display, and an internal 1250mAh rechargeable Li-ion battery. It also features an SD card expansion slot.

The Garmin Nuvi 200W appears to be the same as the Nuvi 200 with a 4.3" display instead of 3.5". Other than that, they are virtually the same and are both basic portable all-in-one navigation system mainly designed for use in vehicles, but also are portable enough to be handheld and featured with a few extra handy applications for travelers.

Target Market

Priced and marketed as an entry-level automotive navigation device, the Nuvi 200W is among the lowest-end within the Garmin's family. Target audience includes entry-level budget savvy users who want a larger display than typical entry-level PNDs.


Available July 2007 per Garmin's press release.

Pricing and Availability

Suggested retail price $266.65 USD per Garmin's web site; however, it is offered by multiple e-tailers online for less than $200 USD.

Volume Estimations

For the purposes of this teardown analysis, we have assumed a 2-year lifetime production volume of 2.2M units (with no changes to hardware - specifically the enclosures).

As a reminder, teardown volume production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed volumes are different by an order of magnitude, minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis because of this.

Market / Sector Performance

Per iSuppli's ""Global OEM Manufacturing and Design Analysis (GOMDA)", iSuppli estimates that the PND market will ship nearly 33 million standalone units in the 2008 global market with a 2006 to 2011 compound annual growth rate of 32.4%. Furthermore, iSuppli estimates that Garmin is one of the dominant players, second to Tom Tom, in the standalone PND device segment with an approximate of 22% market share (as of 2006).

What Is Not Included in our Cost Analysis?

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing and test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

Manufacturing Notes

Garmin's Relationships / Manufacturing

Per iSuppli's ""Global OEM Manufacturing and Design Analysis (GOMDA)", Garmin produces all of its PNDs products in-house. Based on isuppli's research, Garmin is operating manufacturing plants in three cities, two in the US and one in Taiwan.

Country of Origin

This Garmin Nuvi 200W is made in Taiwan (final assembly, that is), per markings on the retail box. However, with respect to subassemblies, unless specifically labeled, it was assumed that PCBAs and plastics, etc are sourced from local suppliers in China. We generally assume that where not noted, that sub-assemblies and some custom manufactured items (plastics, mechanicals, etc.) will be produced in the lowest cost region in the absence of proof to the contrary. We therefore assumed that the PCBA was assembled in China, and that the custom mechanical components were also produced in China. This is not known - and these are merely assumptions.

Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as Bluetooth modules), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.

Remember also that labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. ""Auto" inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pincount of the device. This calculation is affected by country or region of origin as well.

Design for Manufacturing / Complexity

The Garmin Nuvi 200W features a total component count (excluding box contents) of 518 components, of which 28 are mechanical in nature.

Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design.

Design Notes

As with all portable navigation devices, the Garmin Nuvi 200W design features two principal 'hemispheres' - the applications processor, and the GPS receiving / processing circuitry. Though this 200W really qualifies as only one incremental step over the entry-level 200 model, the internal architecture resembles (at it's core at least) the previously analyzed mid-range Garmin 660 and is fundamentally different from the 200.

The core of the 200W is the SiRF StarIII (GSC3f/LP) chip (again - also found in the Garmin Nuvi 660). The applications processor (Texas Instruments - D751623BZHK) is an OMAP processor variant. Additionally, the Garmin Nuvi 200W features 1GB (8Gb) of internal NAND Flash (SLC). Note that with the trends in NAND flash pricing, there is clearly a trend to find more internal embedded memory in favor of bundling SD memory cards, etc.

Here is a summary of the major components used in Garmin Nuvi 200W design.
