Installation of a OBD GPS / GPRS Tracker Using a 306B Cheap China tracker a GiffGaff simcard and the free Traccar software.


I first Purchased the Tracker from the following ebay seller . Item was delivered within 20 days from china. (http://www.ebay.co.uk/itm/111793003206)


I also purchased a GiffGaff Simcard and used a referral link to obtain 5 pounds free credit , please use the following link https://www.giffgaff.com/orders/affiliate/mrluke2097 . As i also get some points :D


You can purchase a special cable for the 306B here http://www.ebay.co.uk/itm/321079001261?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT , at the time of writing this i hadn't received mine so cant vouch that it actually works or how you use it , But its there in case you don't want to text the commands to the device.


Because my OBD port is in view within the foot well of my car i decided to hard-wire this in instead of using the OBD interface , this is the hard-wire kit

http://www.ebay.co.uk/itm/400761384701 , it simply has a special USB connector on the end . You can simply connect this to the fuse box using a fuse Tap




Installation of Traccar

Traccar provides installation procedures on there website for a number for os's. I wont give detailed instructions on how to install traccar as its quite self explanatory . Here is a link to there website


Have a watch of the video and install .


Once installed you need to open a few ports internally and externally . This tracker uses port 5001 for updating Traccar so please open this port and port forward this port number to your traccar internal IP address . If you want to be able to use the web interface from the web externally you also need to open port 8082 and also port forward this to your internal Traccar IP address.

Once installed browse to the web interface of Traccar , login with admin/admin and add the new tracer device . The Devices IMEI is located on the sticker on the device and is around 15 digits long.


Traccar has now been completed .



Installation and Configuration of the device .

1.) Insert the Giffgaff simcard into the device and turn it on ( when sent from china it should have been fully charged , so you should have enough power to configure this device )

2.) Topup your simcard with 10 pounds credit, you will then receive 15 pounds . You can do this by registering for an account online.

3.) Your simcard now has to be configured to connect to Giffgaffs APN , login to your giffgaff online account and obtain the phone number of your new simcard and start a new SMS to the phone number .

4.) Send the following commands



apn123456 giffgaff.com

up123456 giffgaff


adminip123456 YOUEXTERNALIP 5001



Now configured you can now check the status




Give the device a few mins , and it should now connect to GPRS and the GPS light should be flashing . The check123456 command should state that GPRS is on.

Now login to Traccar and hopefully you will be able to see your device , like the following


Once Connect has been established you might want to send the following " less gprs123456 on " , this will stop the device updating the server after 5 mins of parking the car . It will connect again once the car starts moving .
