HALO Unlimited runs on your own Google Maps key, so you navigate on your own free quota — no shared limits, ever. It takes about 10 minutes and stays free for normal use.
Google requires a payment method on your account before map keys work — even for free usage. HALO stays well inside Google’s free monthly limits, so you should not be charged, but the card is required by Google. You can set a budget alert in step 3 for peace of mind.
Go to console.cloud.google.com and sign in with any Google account.
Click the project dropdown at the top of the page, then New Project. Name it anything — HALO works — and create it. Make sure it’s selected before moving on.
Open Billing and link a payment method to your project. This is required by Google for map keys to work.
Optional but recommended: open Budgets & alerts and set a small budget (e.g. $1) so Google emails you if usage ever goes above the free tier. HALO’s normal use stays free.
Open the API Library, search each one by name, and click Enable:
All three are needed. If any is missing, search or place search will fail on the glasses.
Go to APIs & Services → Credentials, click Create credentials → API key. A key appears that starts with AIza… — copy it. That’s your key.
On the key you just made, click Edit and set:
halonavi.com/* so only HALO can use your key.Save. This keeps your key from being used anywhere but HALO. You can skip this and add it later if you’re in a hurry.
On your phone, open halonavi.com/get, pair with the 4-digit code shown on your glasses, then under Advanced · use my own key paste your key and tap Send key to glasses. The glasses reload — and you’re navigating on your own free quota.
