Vehicle Audio Course

# Vehicle Audio Course

Single course, 4-brand scope (Ford, Mercedes-Benz, Toyota, VinFast — **BMW: 0 trims, no data
exists anywhere in this project**). Built on `` and
`` . Verified data only — no vehicle compatibility or wiring
detail is invented for any trim.

## Catalog

- **Ford:** 12 trims, 3 with deep Audio Architecture data
- **Mercedes-Benz:** 9 trims, 3 with deep Audio Architecture data
- **Toyota:** 13 trims, 3 with deep Audio Architecture data
- **VinFast:** 15 trims, 4 with deep Audio Architecture data

Total: 49 vehicle trims, 13 with a deeper Audio Architecture record.

## Lesson 1: OEM system types in this catalog

- **MOST (digital fibre-optic bus):** confirmed for 2/49 trims (Mercedes-Benz C-Class, C300 AMG
 and C200 Avantgarde Plus).
- **A2B, Analog/Hi-Level status (non-MOST vehicles), OEM DSP/Amplifier for the other 47 trims:**
 PENDING VERIFICATION — no vehicle in this project has these confirmed outside the 2 Mercedes-Benz trims.
- **OEM Amplifier:** Burmester, 590W, confirmed only for the 2 Mercedes-Benz trims above.

## Lesson 2: Speaker architecture (where known)

Real per-trim speaker counts/placement exist for 4 VinFast trims (VF3 Eco, VF3 Plus, VF8 Eco,
VF8 Plus) and 2 Mercedes-Benz C-Class trims — see `` for the exact counts,
including 2 unresolved total-count discrepancies (VF8 Eco/Plus: itemized speakers sum to 11,
source claims 13 — flagged, not corrected). All other 43 trims: PENDING VERIFICATION.

## Lesson 3: The Mercedes-Benz W206 MBUX installation constraint (the single most
operationally important vehicle-specific fact in this project)

The MBUX head unit on the current-generation C-Class platform is a single-piece assembly
soldered to the main board — it **cannot** be removed or replaced by traditional aftermarket
methods, regardless of whether the trim has the Burmester system. The only viable aftermarket
paths are a wireless CarPlay dongle or an OEM software upgrade. This affects installation
difficulty and sales conversation for every C-Class trim in the catalog.

## Lesson 4: Vehicle FAQ

`` — 80 real Q&A across the 4 brands. **0 for BMW** — do not
answer a BMW compatibility question from this course; direct to Engineering.

## Exercise

For each of the 4 VinFast trims with known speaker architecture, sketch the speaker layout and
identify which is missing a confirmed mounting location (Answer: VF3 Eco and VF3 Plus — "vị trí
lắp đặt chính xác chưa xác nhận").

## Certification question

Which vehicle brand has zero data anywhere in this project, and what must a dealer/installer do
if a customer asks about it? (Answer: BMW — respond with PENDING VERIFICATION, do not guess or
extrapolate from other German brands like Mercedes-Benz.)

## Not covered (PENDING VERIFICATION)

Non-MOST OEM bus type, non-Mercedes OEM amplifier specs, exact speaker mounting location for
2/6 known-architecture trims, all wiring diagrams beyond the general FX-4/DSP wiring procedure
already in ``.
