Q: Hi,I have a 2006 XC70.
Currently is has the HU650 stereo/CD, and also has factory navigation.
The navigation appears to independent of the radio/CD unit, shares no CD/DVD, shares no display features, but it does play guidance voice sounds.
I would like to upgrade to the HU850 stereo/CD-6 disc with higher wattage output.

Question: Will this HU850 on ebay plug-and-play in my car? Are the connectors and wiring the same?
I realize speakers are different, and more of them, but I can upgrade or replace my current speakers.
Thanks-

A:Yes, it will be plug and play, hu-650 is using external amp as hu-850, you will have much better sound and 6 cd changer, it is a very easy upgrade and I have done many myself, you don’t have to replace the speakers it will be better sound with your existing speakers

thank you
Patrick
