The product is only certified and designed for being installed inside the handlebar of a bicycle although it can fit other spaces aswell. The antenna needs free access to sky in order for the tracker to function well. The signal cannot be blocked because of for example aluminium or carbon which is the case when the BikeFinder is put in other spaces of the vehicle than the handlebar.
The BikeFinder has to be installed correctly in order to function and give out a good signal. Read the instructions on how to install the tracker correctly on the instruction manual inside of your product package.
