No no, there is no error in the title, your unit can also serve as a thermometer through the RDS module 10 BI Automotive Digital. A handy little device for low cost cars that lose some features such as Indoor / Outdoor Thermometer!
To lower the selling price, many cars at low prices no longer have a thermometer inside and outside. Yet this little feature is handy to adjust the temperature of the air, since the button hot / cold is rarely graded. BI Automotive is a German manufacturer specializing in improving the original facilities and improving the comfort of the car. Digital RDS module 10 is a small electronic box measuring indoor and outdoor temperature. It is also warning of ice. For the indoor temperature, a sensor is built into the case. To the outside temperature, it will place the probe provided in the grille. This box plugs into the antenna connector of the radio and sends its information through the RDS. We just have to tune in a station of agreement and the store in the car. At any time, you can zap the preset station and see the temperature, and possibly adjust your air conditioning. The detection of ice is indicated by a small red LED. This little box BI Automotive sold around 90 Euros.
