Ok, so Iím sure there are others out there that have been thinking of installing an aftermarket Navi? I just happen to be in the middle of doing it and I have some info and need some advice. I have purchased an aftermarket pop up display (really nice BTW) the unit comes with a factory mounting bracket and a speaker grill replacement. Anyway, now that I have found the display I obviously needed to figure out what I was connecting to it? After spending a bit of time on the phone with Kenwood USA I went with the following items. 1. KOS-V500 (control/menu), this unit is basically home base for all the hardware. It gives you an options menu and remote control. Connected to this unit will be (all from Kenwood) 2. Bluetooth (parrot makes for kenwood) 3. Hideaway Navi (Garmin makes for Kenwood) 3. XM Sat unit 4. Rear backup camera 5. Audio/Video Ipod connector (also Kenwood. 6. DVD video (connected to headrest monitors as well). All of these components actually work very well together.

Here is the question? My installer is questioning how the audio aspect is going to play through the speakers? I called Kenwood and they told me to have the installer splice into the speaker lines coming into or from the Amp. I'm not sure I understand that? My installer says that isn't possible. Now I'm getting a little nervous. Someone, either the installer or the Kenwood rep doesn't know what they are talking about??? So I was thinking, what about using the AUX input? The KOS-V500 has very simple RCA jacks for the audio output. So it seems, in theory, that we should be able to connect the RCA jacks from the KOS-V500 to an input module into the AUX port in the back of the radio..? WILL THIS WORK?? There doesn't seem to be that many modules out there. I found a cheap one on ebay.

Not sure if it will work? Also found another one at installer.com.

The last one I found seems to use the CD changer some how?

Has anyone had any luck with any of these units??? I'm also told that some dealer programming may be necessary to activate the AUX input section on my radio? Also not sure if thatís true.

I would really love some advice. Let me know your thoughts. Thanks

1/ Option mentioned by Kenwood:
This is actually possible. Kram telecom (www.kram.dk) for instance provides wiring and a relais system to put between the existing amp and speakers.
Upon power or short on their mute connection, these systems will cut off the existing speakers and switch to the alternative source, also connected to their relais box.
Generally these systems are meant for handsfree calling and will only output sound to the front speakers. The alternative source also should be amplified, as no builtin amp is present in the relais box. Should not be chosen if in need for quality audio.

2/ Option 2: Ebay 8 pin plugin item: 8pin connector is typical for MELBUS, not for XC90 My08 which features MOSTBUS. Unusable

3/ Option 3: NAV.TV MOSTAUX-VOL (http://www.nav.tv/category/7/85/205)
Links up directly to the Mostbus fibre optic loop of the XC90's audio system. This input is actived upon providing 12v to a connection on their mostaux-vol box.
Seems like cheapest option for descent audio, completely controllable from integrated volvo sound system.

4/ Dension Gateway 500 (http://www.dension.com/index.php?pageID=11)
Also directly linked to Mostbus fibre calbes. Dension seems to limit compatibility to Volvo's XC90's from 2002 till 2006, High Performance and Premium sound system, without AUX input, with cd changer. Volvo support seems limited, few times mentioned on site.
If functional, more expensive than nav.tv

In any case, it is clear you will have to contact these companies yourself to ensure compatibility before ordering.

Good luck.
