XM Install Update

HELP

Next to dip switch on the side of the iMIV is an LED light. Should that be on when there is power going to the iMIV?

Prior to attempting to install an XM radio my iMIV was working. In doing the install of the XM, I tapped into the iMIV power and ground wires (green for ground and the red with black stripe for power).

Now, neither the iMIV or the XM work. The LED on the iMIV does not on. Volt meter reading into the iMIV plug is "0".

I have pulled the taps and soldered all the connections but still the iMIV and XM do not work and show no sighs of power on the volt meter.

I hate to pull the HU again...too hard to get back in.

Should I run another switched power line from the fuse panel on the drivers side? Any recommendations for which fuses are switched?

All is not well in the land of

Sounds like you blew a fuse? I know my sirius unit is 5 volts and needs its power adapter to convert the 12v to 5v. does your xm unit require the same 5v? and if so did you wire in the whole xm power adapter, or wire 12v strait to the unit?

Re: (adam3914)

I thought fuse too. The power and ground cpme off the OEM wire harness that I purchased when I installed the iMIV. This all plugs into the HU. The HU works. I do not think there was an inline fuse on the wire harness that I got from iMIV. Anyone remember if there is an in-line fuse in this harness?

If yes, it is buried behjind the HU.....arrrrrrrrrrrrrrrgh I'll have to take out the HU to get to it.

Yup-there is an inline fuse...

My money is on that.

Re: XM Install Update

I was determined not to pull the HU.. I ended up using add-a-circuit and ran a new hot line from the fuse box on the driver's side of the dashboard to the iMIV and XM. I used wire from a coat hanger to fish the wire over the transmission hump with no problem. I ran a ground to the gounding bolt on the door frame.

Mounting the antenna and controller was very easy. I used velcro to mount the antenna inside the car on the glass in the upper right corner of the front window. For the XM controller, I slid a small piece of plexiglass between the surround molding of the sun roof and the ceiling console. I used velcro to mount the XM controler to the plexiglass. The cable for the controller runs under the front edge of the ceiling panel and down the A pillar. The antenna cable runs down the A pillar too.

All the components (iMIV and XM receiver) meet in the small area under the dash, between the glove box and the passenger door. Both are accessible from the door that is at the passenger end of the dashboard.

All worked well yesterday afternoon. Good XM reception. Then, I went out last night and the iMIV was not working (

arrrrrrrrrrgh). There was power to the XM put no iMIV connection to the HU. Hopefully one the iMIV connections is just unplugged. I will check tonight if it is not raining.

**************
Are any of the fuses in driver's side (end of the dashboard) fuse panel switched? If not, what about the fuse panel over the driver's footwell?

Re: XM Install Update (Ozzie)

You might need to check all your wiring for a short that is blowing the imiv fuse?

Re: XM Install Update (MrTippy)

Thanks Mr. Tippy, that was my initial thought until I realized the iMIV and XM are running off the same 10 amp fuse. The way I have wired it, there is no in-line fuse for the iMIV. All the connections are shrink wrapped and taped.

The hot from driver's side fuse box runs to within 2 feet of each device where it splits into two: one lead for each device. The XM is still powered. I have not checked the iPOD. If the iPOD is "live" than the iMIV cable to the HU came out. That is what I am hoping is the case.

On the need for power, this morning I read that the iMIV needs constant power. The XM needs switched power. That means I need to redue the wiring.

Any idea where I'll find a switched power source without pulling the HU?
TIA

Wasn't the original fuse for the imiv more like 1-3 amps? I don't know what the iMIV is rated for, but if Edwin designed it with a low power inline fuse, I would keep it in there.

I can get my HU out in 15/20 minutes and reinstall it in 20 mins or so. My recommendation is to take advantage of the existing ice wiring and avoid the wiring shortcuts--they are not really saving you anything.

There ought to be switched sources in the fuse box, e.g. the 12v accessory outlets, the aux amp; check your owners manual for the assignments.

Re: XM Install Update (MrTippy)

Mr. Tippy

Good news --- the cable to the HU from the iMIV box was loose. I plugged it back in and all is working as intended!!

I'll send an email to iMIV and ask what the amperage should be for an in-line fuse going to their box. That install will be easy to do.

For switched power for the XM, I'll see if the RTI fuse is switched. I'm already tapped into the telephone circuit and am surprised that it is not switched. For now, I'll use the on/off switch on the XM controller.

I am glad to hear you don't hae the HU install issues that I have. My HU has too many extra cables: bluetooth, accessary connection, iMIV cable, Escort cable, and amp cable. No matter how I cram the cables up, down and to the side, getting the HU in is a real struggle and took four hands the last time. If there is a trick I'm missing, please let me know.

Thanks again for the ideas.

Re: XM Install Update (Ozzie)

Good news indeed.

You have a few more wires behind yours than I do and there is not much room to begin with, that just may be the difference between our two cars.

I had my HU to iMIV (actually it was the oem cd-changer) cable become disconnected at the HU once. All I could think of was that it was loosened at the dealer when they repaired my A/C and then it evetually worked itself loose.

Re: XM Install Update (MrTippy)

Follow-up information

I heard from Matt at iMIV. The Sensolution power cable that hooked the iMIV into the HU's power did not have an in-line fuse because the radio is appropriately fused.

If getting power from another source, the in-line fuse for the iMIV should not exceed 3 amps.

Still looking for a fuse box site on the XC70 that is switched.

Re: XM Install Update (Ozzie)

On the 2005 XC70, switched power can be found on fuse #11 in the driver's footwell (auxiliary power ports).

XM install is mostly done. Still playing with antenna location. Moved the antenna to dash top near the front wind screen.

There is "pop" thru the speakers when the XM comes on. The power for the XM and the iMIV comes from separate fuses.
