Q:Hi I installed a used second hand GPS reader on my Volvo xc90 2005 24400 scmq diesel t5. It doesn\’t accept from the car do you now why? Have I to register it or make something about the new code?

A:did you install the same one, with the same part number? it should work right away if you installed correct gps reader or the one you have purchased simply doesn’t work,

thank you
Patrick
