Target Market

Toyota Aftermarket

This is Toyota Original Accessory built by Panasonic



This design is currently available from Toyota - and as an aftermarket accessory is assumed to have a shorter product lifecycle than OEM installed units. This should be a fairly recent design.

Pricing and Availability

65000 Yen MSRP Toyota Japan

Japan Market

Sold by Toyota dealers in Japan.

Volume Estimations

1,800,000 Annual Production Volume
2 Product Lifetime (Years)

For the purposes of this teardown analysis, we have assumed an Annual Production Volume of 1800000 units and a Product Lifetime Volume of 2 year(s).

Teardown volume and 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.

Panasonic DAN-W62 Navigation Head Unit Cost AnalysisPanasonic DAN-W62 Navigation Head Unit Cost Analysis

Not Included in 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 with basic 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.

We do provide an Excel tab 'Overall Costs' where a user can enter their known pre and post production costs to build a per unit cost reflective of theirs actual expenditures.

Country of Origin

For the purposes of this analysis, we are assuming the following country(ies) of origin for each level of assembly, based on a combination of 'Made In' markings, and/or assumptions based on our knowledge of such equipment.

Box Contents - Japan
Display / Touchscreen - China
GPS PCB - China
Main PCB - China
Misc PCB Assemblies - China
Other - Enclosures / Final Assembly - Japan

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 combo 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.

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.
