The phrase "getting Go" in the trade means Google has cleared the product — it has passed formal testing and final review and been issued a certification ID, so it can enter mass production and ship. Before that clearance sits a four-stage road of access, development, self-test and formal testing; after it comes production consistency and change management. The whole chain is not a single test but an ongoing relationship.
This piece walks the nodes in order. We cover only what each node requires and where it most often jams — not a separate time-and-cost breakdown.
Start by registering a Google enterprise developer account; the company information must match the business licence and qualification documents exactly. A one-character difference in the company name, or a full-width versus half-width bracket, can get the application rejected, and re-signing the loop is common. The account is enterprise-level — do not file a project under a personal account.
The agreement layer is where people get confused fastest. Handheld devices that preload Google apps follow the MADA; a head unit is not in that class, and filing under the wrong one gets returned outright. A pre-installed AAOS vehicle system that touches Google Automotive Services (GAS) authorisation follows a separate set of terms; as for the commercial agreement for Android Auto projection certification, Google has not published a name for it — the trade calls it ADA, and you sign whatever the current text the partner channel supplies.
Lock the path at the same time. A pre-installed AAOS touches CTS/VTS and GAS authorisation; an aftermarket projection runs only Google's AA compatibility test, not CTS/VTS. The test items, documents and contacts differ between the two roads, so sort which one you are on at project kickoff — mixing them means a wasted round.
Hardware selection is the key step. Wireless projection relies on Wi-Fi plus Bluetooth; prefer Google pre-certified modules, and finish the BQB and CE-RED work on the RF side early. The exact generation threshold follows Google's current compatibility requirements — do not copy a version number off the internet. Non-pre-certified modules raise the RF rework rate sharply once they enter the lab, and a component swap can throw the whole schedule off.
In the self-test phase, run the AA compatibility test items locally first: connection stability, audio quality, touch latency, voice wake-up and interference resistance. Voice wake-up latency, recognition rate under high-SPL noise, and continuous connection success rate are the three items that fail most often.
Build a defect log and track each failure category per round, so you can show pass evidence before the lab receives the sample. Saying "it runs fine" is useless — formal testing is charged per round, and every extra round is money out the door.
① Samples go to a Google-authorized lab. Formal testing is billed per round, and one round runs on the scale of weeks, covering experience, audio, connection stability and extreme-temperature conditions. Only a pre-installed AAOS stacks CTS/VTS on top; aftermarket has no such layer.
② After testing passes, the report together with the self-test data goes to Google for final review — again on the scale of weeks. Pass and you get the certification ID, the "Go" the trade talks about.
③ How long the certification lasts deserves care. The trade does not speak with one voice on old annual re-review versus the current rule — some say long-term valid, some say per-year. Go by the current document from your partner channel; do not promise a customer using second-hand claims.
① Production hardware and software must match the archived sample. Changes to the main controller, a wireless module swap, baseband firmware moves, or a major antenna-architecture change usually trigger re-evaluation; large changes to the screen or display driver can also draw a re-evaluation request. This list reflects common industry practice, not a published Google clause — the current policy always wins.
② You must also keep pace with Google's mandatory version steps. A major OS version iteration brings new compatibility requirements, and an old project that cannot keep up loses its adaptation permission. Compliance is a continuous act, not something that ends on certification day.
For Android Auto projects, BlueAsia fixes the path and the hardware list once at the kickoff stage — pre-install or aftermarket, which agreement line, whether the module sits on the pre-certified list, and where the RF certification sits — then folds RF, USB compliance and head-unit certification into one schedule so the product is not split into several separate submissions. The cost is billed per round, so move only after that is set.
