2001 V70XC: Can you remove the head unit but keep the integrated phone?

[Mastiha]

Hi,

I own a 2001 V70XC with the HU-803 head unit and I also have the integrated phone..

I read the article found here (http://www.swedespeed.com/news/publish/Features/article_147.html) and I wanted to do something
similar.

I've made two posts already on www.v70xc.com about it
(http://www.v70xc.com/forums/showthread.php?s=636bf7fdd9b7d15b5d2f2d21f2684571&t=6008 and
http://www.v70xc.com/forums/showthread.php?s=636bf7fdd9b7d15b5d2f2d21f2684571&t=6005).

My main concern is whether the integrated phone is still usabe if the head unit is replaced.

Thanks for your help.

Regards

Mastiha
