| This is a tiny bluetooth GPS receiver which I | | | | phone, please be aware of this before buying |
| bought from Mobile Fun Ltd, I bought this to | | | | this device as you are sure to encounter |
| connect to my O2 XDA 2i PDA and it cost | | | | problems. |
| around £40. I was intially looking on | | | | |
| google for cheap GPS receivers and this came | | | | Key Features |
| up as the cheapest. I thought at that price | | | | |
| they'll be a catch, and the catch usually | | | | Compatible with TomTom, Navicore, and all |
| being poor performance, but I was pleasantly | | | | major GPS software packages. |
| surprised! This thing really does work, and | | | | |
| works well! | | | | 12 parallel satellite-tracking channels for |
| | | | fast acquisition and reacquisition. |
| After searching for initial reviews on this | | | | |
| device I came up with very little other than | | | | Provides superior navigation performance in |
| the reviews from Mobile Fun Ltd, which I was | | | | city environments. |
| reluctant to trust for fear of them being | | | | |
| somewhat biased. I thought for £40 I'll | | | | Built-in rechargeable Lithium-polymer battery |
| take a chance and so bought it, all credit to | | | | provides more than 10 hours of constant use. |
| Mobile Fun the receiver arrived the very next | | | | |
| morning. Upon opening the box I was a little | | | | Unit can be charged with the included car |
| disappointed, all the there was by means of | | | | charger while still in use. |
| instructions was a small sheet of paper that | | | | |
| had been loosely translated from Japanese to | | | | Mini-USB charger compatiblty, charge not only |
| English by a dyslexic toddler. You can | | | | the Bluetooth GPS Receiver but also |
| download the user manual from here and the | | | | compatible PDAs & Smart Phones with the same |
| Tomtom pairing manual from here. After | | | | charger. |
| following these instructions you will have it | | | | |
| set up in no time. Another thing I noticed | | | | 3 colours LED to show the status of Bluetooth |
| was that there is no manufaturer's name or | | | | GPS/Power activities of this device. |
| marks anywhere on the device or the | | | | |
| packaging, which makes searching for support | | | | Specifications |
| quite difficult. | | | | |
| | | | GPS receiver: L1, C/A code, 12 channels |
| A nice touch with this little device is that | | | | |
| it is supplied with a battery that is common | | | | Tracking sensitivity: -152dBm (average) or |
| to a lot of Nokia phones (3.7V 850mAh | | | | better |
| Li-polymer battery, BL-5C), a quick search on | | | | |
| ebay means that you can get replacement | | | | Acquisition sensitivity: -139dBm (average) or |
| batteries for these receivers for about £4 | | | | better |
| which is good to know should you need one. | | | | |
| | | | TTFF (Time to First Fix): Cold Start: 50s |
| What's In The Box? | | | | (average) / 60s (95 possibility) |
| | | | |
| Bluetooth GPS Receiver x1 | | | | Hot Start: 2s (minimum) / 6s (95% |
| | | | possibility) |
| 12v In Car Adapter (USB) x1 | | | | |

| | | | |
| Installation | | | | NMEA output protocol: V.3.01 |
| | | | |
| Provided you follow the limited instructions | | | | Baud rate: 38400 bps (8-N-1) |
| for pairing with your device, and the Tomtom | | | | |
| setup instructions, you should be up and | | | | Datum: WGS-84 |
| running in less than 5 minutes. I have only | | | | |
| charged the receiver once since I bought it | | | | Type: GGA, GSA, GSV, RMC |
| about 2 months ago, the battery just seems to | | | | |
| last forever! The supplied in car charger and | | | | Power consumption: 75mA (average) |
| USB cable means that the receiver can be | | | | |
| charged on the move from a 12v source and can | | | | Bluetooth: Bluetooth version 1.2 compliant |
| also be charged from any PC or laptop. From | | | | |
| cold start up the receiver aquires a usuable | | | | Class 2 operation (up to 10 metre range) |
| GPS signal exremely quickly, quicker than | | | | |
| most of the really expensive GPS receivers | | | | Serial Port Profile (SPP) |
| that I've come in contact with. The device is | | | | |
| extremely small and can easily fit into any | | | | Output terminal: Type B Mini-USB (TTL Level) |
| space in your car, or even your pocket if | | | | |
| you're using it for walking or cycling. | | | | Antenna Type: Built in Patch Antenna |
| | | | |
| One small problem I did have is that when | | | | Battery: 3.7V 850mAh Li-polymer battery, |
| using it with my XDA 2i the Tomtom software | | | | built-in charger |
| would often freeze and cause me to stop the | | | | |
| car, reboot my phone, then carry on my | | | | LED: Power (red), GPS (green), Bluetooth |
| journey. At first I thought this was the | | | | (blue) |
| result of the XDA losing its connection with | | | | |
| the bluetooth receiver and hence confirming | | | | Dimension: 64(L) x 39(W) x18.5(H) mm |
| my fears about the price of this product. It | | | | |
| quickly became apparent that this was not the | | | | Operating temperature: -20°C ~ +60°C |
| case and it was in fact an issue with my PDA | | | | |
| and the Tomtom software. | | | | Storage temperature: -20°C ~ +60°C; |
| | | | Battery: -20°C ~ +45°C |
| I quickly discovered a workaround for this | | | | |
| issue between the Tomtom software and my XDA | | | | Conclusion |
| that enables the whole system to work | | | | |
| flawlessly. I shall write a 'how to' on this | | | | A great little device that performs well |
| workaround shortly as I'm sure many other XDA | | | | beyond its price range. Check if there is any |
| 2i users share the same problem. | | | | known issues with your device and bluetooth |
| | | | GPS receivers before purchase as this will |
| I do know that there is a known issue when | | | | save you a lot of headaches. The only thing |
| using any bluetooth GPS receivers with the O2 | | | | that lets this product down is a lack of |
| XDA 2 (note not XDA 2i) due to the bluetooth | | | | documentation and online support, other than |
| stack settings that are shipped with the | | | | this well worth the buy! |
