I am really confused about metra kit.
I always wanted double din 7" monitor stereo in my car but corksport was very expensive for me.
The price of Metra seems to be ok fine with me.
My car is equipped with BOSE and climate control. (will i have the control of ALL Climate Control features (temp etc.))
Are there any specific requirements i will need have from the unit?
I am planning to install JVC KW AVX710.
It has a 2.5V line output.
Would i need more ( in an Alfa romeo forum they mention that 5V output is better for BOSE amp)?
The JVC AVX810 has 5V line output.

Apart these two (metra kit and jvc) what else i will need to complete the install and make everything works?


Thank you!
