Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The market is built upward from global light-vehicle production volumes reported by OICA, split by the embedded, tethered and integrated connectivity attach rate for each vehicle class, and multiplied by the average realised price of the telematics control unit or connectivity module fitted at that attach point. Aftermarket and services revenue is added separately from unit shipments of retrofit telematics devices and reported subscriber counts for telematics and infotainment services. This bottom-up build is then checked against the connected-services and telematics-segment revenue disclosed in the annual filings of Continental, Bosch, Denso and Harman; where the two diverge, the attach-rate or per-unit price assumption feeding the bottom-up build is corrected, not averaged against the disclosed figure.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary interviews target the commercial and technical roles that set connectivity strategy inside OEMs and their tier-one suppliers: platform and infotainment engineering leads, telematics control unit procurement managers, connected-services product managers, and regulatory affairs staff responsible for emergency-call and cybersecurity type-approval filings. On the demand side, fleet and insurance telematics buyers and aftermarket installer networks are sampled to check attach rates and subscription renewal behaviour outside the OEM channel. Sampling is weighted toward Germany, Japan, South Korea, China and the United States, the five countries where light-vehicle production and connectivity-module manufacturing are most concentrated, with lighter coverage of emerging-market fleet operators to check aftermarket assumptions in Latin America and the Middle East.

Secondary sources, this report

Desk research draws on OICA and national automotive-association production and registration statistics, customs trade data filed under HS code 8526 and 8517 for telematics and communication modules, and 3GPP and ETSI type-approval and certification registers for cellular and V2X modules. Regulatory filings tracked include the type-approval registers covering mandated emergency-call systems in relevant markets and vehicle cybersecurity regulation filings. Company-level checks use segment revenue disclosed in the annual reports and investor filings of Continental, Bosch, Denso, Harman, NXP and Infineon, alongside GSMA connected-vehicle shipment reporting for embedded SIM and module volumes.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from the projected attach-rate curve for embedded connectivity across new light-vehicle production, anchored to OEM platform-refresh cycles and the phased rollout of 5G-capable modules replacing 4G/LTE as the default fitment. Regulatory mandates for emergency-call and safety connectivity are treated as a step-change in specific markets rather than a smooth trend, applied in the year each mandate takes effect. Pricing is assumed to decline per module on a learning-curve basis as volumes scale, offset by rising average revenue per vehicle from added services. The forecast holds if 5G network coverage and OEM platform timelines proceed broadly on their currently announced schedules.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs are back-tested against recorded connectivity attach-rate growth and telematics-segment revenue growth reported by major suppliers over 2020-2024, checking that the modeled historical path does not diverge from what those companies actually reported. Segment-level shifts, including the transition from tethered to embedded connectivity and the rising share of 5G-capable modules, are reviewed against current OEM platform announcements to confirm the pace assumed is not ahead of what has actually been announced. Sensitivities were tested on the connectivity attach-rate assumption and on the timing of 5G module rollout, since these two assumptions move the forecast total more than any pricing assumption.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest in North America, Europe and the leading Asia Pacific markets, where OEM connectivity attach rates and supplier telematics revenue are both reported with enough regularity to cross-check directly. It is weaker in the aftermarket and in Latin America and the Middle East and Africa, where retrofit device shipments and subscription renewal rates are thin and inferred from adjacent proxies rather than direct reporting. A structural risk that would force a revision is a slower-than-assumed 5G network buildout, which would push embedded-module upgrades and associated service revenue later than modeled here.
