no, not the steering wheel, or any other whitty comments! lol.
Just put a deposit down on an 08 bravo sport mjet 150 in maseratti blue :) - while test driving it i noticed a black 'button' type thing in the middle of the dash right near the windsreen - any idea what it is? its about 7mm high and circular?

...and yes, i know i have to change my forum name! lol

Thanks in advance!
 
Solar sensor
The solar sensor is located in the top part of the dashboard at the base of the windscreen and its function is to transform the light signals (lux or kcal/m2) into a proportional linear electrical signal. The sensor is a particular type of diode (photodiode) which can vary its conduction depending on the quantity of light it comes into contact with; in practice, the incident light which comes into contact with the photodiode small lens releases electrons from the crystalline structure.
As a result electrons and free gaps appear in excessive numbers.
They are directed towards the photodiode spatial or junction zone (NP) and increase the junction current (photoelectric current) in proportion to the intensity of the light. In order to achieve a very high response speed, the photodiode is equipped with a small lens which has the task of improving the focus of the light on the semiconductor junction (NP) which makes up the photodiode.
The control unit (NCL) using this signal alters the temperature parameters decreasing it and at the same time acting on the distribution of the air.

ok cool, thanks for that! thought it might be an alarm or something?
so would my new standard bravo sport have this feature or is it just the cap where the sensor would be - the car has standard air con.


Also where on the dash is the sport button?????

It's related to atomatic climate control. Not for manual AC.

Mjet doesn't have Sport button.
 
oh right! didnt realise only tjets had sport mode :( never mind, was well happy with the performance anyways! the car i'm getting only has one key - would that be a problem?

thanks for the advice!!
