Combining the BT-821’s Bluetooth wireless technology with a Bluetooth enabled devices such as Smartphones, PDA’s or laptops which support Serial Port Protocol SPP (regardless of their operating system) and your favorite navigation software (street, topo, ocean, aviation), you can create a sophisticated navigation system at a fraction of the cost of larger dedicated navigation units.The BT-821 offers up to 23 hours of continuous use from a single charge, making it the ideal GPS for extended navigation trips, whether on the road or on the trail. Battery usage is substantially increased by having a built-in auto shut-off feature that power’s off the BT-821 after 10-minutes of no active connectivity with the host device. Should the BT-821 ever be accidentally left on when exiting a vehicle, or within a backpack, the auto shut-off feature will power-off the GPS receiver to conserve battery resources.The BT-821 comes complete with a 12VDC cigarette lighter adapter for in-vehicle charging.

CD-ROM (User Manual & GPS Info Test Utility). 110VAC wall charger sold separately.How to use: 1) Pair your GlobalSat Bluetooth GPS Receiver to you phone, first. (Pairing code: 0000).2) Enable "Allow mock locations" on your device by going to Device Settings > Applications > Development > turn on or check"Allow mock locations". If you can't find Developer Options in your settings. 3) Then open the GPSInfo App. 4) Tap on "Choose Bluetooth GPS", and select the GlobalSat Bluetooth GPS receiver (listed as "BT-GPS-XXXXX"). 5) Check the box “Location Provider Options” and it should change to: "Bluetooth GPS to replace internal GPS". 6) Tap on "Start/Stop GPS". 7) You should then be able to see the GPS data by tapping on "NMEA Data" and "GPS Data". If you want to record the NMEA log, check the box "Enable/Disable NMEA log". The NMEA Log will be recorded in "/sdcard/nmea".Then leave GPS info running in the background and use your navigational app. NOTE: Once you pair the Bluetooth GPS to your PC, it is not supposed to be always "connected". Unfortunately, due to restrictions put on by Apple, Apple's iOS devices (iPad/iPhone/iPod Touch) do not support our external Bluetooth GPS Receivers. Review: worked like a charm with my android tablet I got this at a reasonable price. - Not the thing for the non-tech-savvy, there are no step by step instructions included to hold your hand. But if you look up model number you will find software to enable you to connect bluetooth GPS to your mobile device. I downloaded "bluetooth GNSS" from the android play store, enabled location spoofing on my Lenovo P11 tablet, and was up in 10 minutes , including a couple of minutes for the initial satellite lock. Installation on my galaxy phone was faster. When I am in an "asphalt canyon" area , the extra precision is much appreciated. My tablet's GPS is useless even among 4 story buildings near downtown boston If you are even a little technically inclined and have 15 minutes , you can do this. Very accurate and necessary for using my Lenovo P11 android tablet, because it's gps is sloppy. I cannot raddress long term battery durability (number of cycles it will take a charge), but the battery life per cycle is well over 8 hours, and the battery is user replaceable. I got this for a great price on desertcart but scarcity now brings increased expense. Review: The ad says this device works with 'Bluetooth enabled smart phones'.

Also, the device only comes with a car charger. Since the device requires a special connector instead of the more universal Micro-USB cable, there is literally nowhere else it can be charged. This makes the BT-821 highly unusable compared to other devices. ## Features - Package Dimensions: 14.478 cms (L) x 18.541 cms (W) x 14.478 cms (H) - Product Type: Gps Or Navigation System - Package Quantity: 1 - Country Of Origin: Taiwan ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005QXYEA8 | | Additional Features | Bluetooth | | Are Batteries Included | Yes | | Battery Average Life | 23 Hours | | Best Sellers Rank | #863,509 in Electronics ( See Top 100 in Electronics ) #877 in Handheld GPS Units | | Brand | GlobalSat | | Built-In Media | BT-821 Bluetooth GPS Receiver, 3.7 Volt Li-Ion Rechargeable Battery, 12VDC Car Charger, CD-ROM (User Manual & GPS Info Test Utility) | | Compatible Devices | Smartphone | | Compatible with Vehicle Type | all-terrain-vehicles; utility-vehicles; off-road-motorcycles; street-sport-motorcycles; street-cruiser-motorcycles; street-touring-motorcycles; street-motor-scooters; snowmobiles | | Connectivity Protocol | Bluetooth | | Connectivity Technology | Bluetooth | | Control Method | Voice | | Customer Reviews | 3.8 3.8 out of 5 stars (151) | | Display Type | LED | | Global Trade Identification Number | 00795945021905 | | Human-Interface Input | Touchscreen | | Item Weight | 8.8 ounces | | Manufacturer | USGlobalSat, Inc. | | Map Types | Satellite | | Model Name | GlobalSat | | Mounting Type | Dashboard Mount, found in image | | Operating System | Android | | Screen Size | 1 Inches | | Supported Satellite Navigation System | GPS | | Touch Screen Type | Capacitive | | UPC | 795945021905 | | Warranty Description | Usglobalsat, inc warrants globalsat technology hardware products against manufacturing defects in material and workmanship under normal use for a period of one year from the date of original purchase. | ## Product Details - **Battery Life:** 23 Hours - **Brand:** GlobalSat - **Connectivity Technology:** Bluetooth - **Map Type:** Satellite - **Model Name:** GlobalSat - **Mounting Type:** Dashboard Mount, found in image - **Screen Size:** 1 Inches - **Special Feature:** Bluetooth ## Images ![GlobalSat BT-821C Bluetooth GPS Receiver - Image 1](https://m.media-amazon.com/images/I/619YBrXuk9L.jpg) ![GlobalSat BT-821C Bluetooth GPS Receiver - Image 2](https://m.media-amazon.com/images/I/51Smp3BC9BL.jpg) ![GlobalSat BT-821C Bluetooth GPS Receiver - Image 3](https://m.media-amazon.com/images/I/610gX+DFURL.jpg) ![GlobalSat BT-821C Bluetooth GPS Receiver - Image 4](https://m.media-amazon.com/images/I/61nJkKBzJeL.jpg) ![GlobalSat BT-821C Bluetooth GPS Receiver - Image 5](https://m.media-amazon.com/images/I/612ZTw9DpwL.jpg) ## Available Options This product comes in different **Customer Package Type** options. ## Questions & Answers **Q: Can multiple devices connect at the same time?** A: Connects to one device at a time. The Bad Elf GPS can support up to 5 Bluetooth connections. **Q: WHAT PASSCODE DO YOU USE?** A: I have found that these bluetooth gizmos either use no code, 0000, or 1234. One of those ought to work. **Q: Will this work with a Samsung Galaxy Tab 4 8.0?** A: I looked up the specs on the Samsung Galaxy Tab 4 8.0. It does have Bluetooth on it. The BT-821C should work with it. I am using this on an Addroid tablet with Android 4.1 and it works great. Here is what you need to do:You will need to install an app called "GPSInfo" from google play, and your favorite navigation app (mine is CO-Pilot Premium USA)Pair the bluetooth device with 0000 as the pairing code. Set to allow MOCK location from developer settings.This is a great GPS receiver and small enough to fit about anywhere. **Q: Does this work with Fire he 8 for Pokémon go?** A: I dont know but it does work great on farm equipment to link to tablets ## Customer Reviews ### ⭐⭐⭐⭐⭐ worked like a charm with my android tablet I got this at a reasonable price. *by B***R on August 24, 2021* Not the thing for the non-tech-savvy, there are no step by step instructions included to hold your hand.

That's flat out wrong because it doesn't work with Apple devices. Also, the device only comes with a car charger. Since the device requires a special connector instead of the more universal Micro-USB cable, there is literally nowhere else it can be charged. This makes the BT-821 highly unusable compared to other devices. ### ⭐⭐⭐⭐⭐ Nice device, use it to add GPS to a device, but not to fix a garbled phone compass *by L***E on February 4, 2019* This is a nice device, the battery seems to last forever since the receiver goes to sleep automatically. It will help your mobile phone get GPS if you're using it behind a waveproof windshield or inside a Faraday cage. But it won't help you if you suffer from an phone compass showing random directions. To correct that, set your Maps "north up" and use an actual compass to turn your phone the right way and find the street you need to take. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/1014749-globalsat-bt-821c-bluetooth-gps-receiver](https://www.desertcart.hk/products/1014749-globalsat-bt-821c-bluetooth-gps-receiver) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-04-23*
