Good Kit; Great Suport

This kit was easy to connect. My radio sounds great and the Bluetooth works fantastically. Even better, the tech support. They talked me through a connection problem, even sent me photos to guide me. Great support!

The only game in town.

The pins for the stereo harness were not properly seated in the connector, and push out when the connector is mated to the car's harness. I ordered another one to replace the first one, after I noticed this. The interface appears to work, with the exception of the parking brake, which worked intermittently. I am going to make sure that I flash upgrade the box, and then try the new one to see if it fixes the problem.

Check for updates first thing!

Verified employee purchase (What's this?)

Did the install for my 2012 Fiat Abarth on a cold, wet Sunday in nowhere Wisconsin. Steering wheel control module would not work. Called Clint at Crutchfield and tried a couple fixes to no avail. Clint sent a link to manufacturer to download/install updates. Unit needed 200 updates! Took over 2 hours for this so we ran out of daylight and had to patch the car up, head home, and work into the early hours of Monday.

Pros: Straightforward to connect once updates, call support was awesome

Cons: Time to download/install updates was 2+ hours alone

The product itself is good. its tecnically everything you need--if you already know what you are doing. The directions leave a lot to be desired and while i spliced everything correctly, the little black "mystery box" didn't work properly. I had to take it to a radio install place and he had to manually program the box.

This worked great. I didn't even need to program it. Just connected the wires together and even had the wire harness for a the steering wheel controls and they worked flawlessly as well! I highly recommend this procuct!

Pros: simple to install, no programming,

Cons: if you don't have enough room behind the dash, it is a little big. My fiat 500 fit, so it might fit everywhere.

It does work with a lot of trouble shooting

Verified employee purchase (What's this?)

Great product, works as it should in keeping the factory steering wheel controls, but the instructions were horrible. Once I figured out the wiring diagram and understood the LED flashing light sequence. then you had to do one more step that was not very clear at all. If you get all the correct LED light flash sequences you then have to hold the volume up button for 20 seconds. Make sure your stereo is off!

Pros: Works great once for figure it out.

Cons: Very poorly written instructions.

Don't buy for Fiat 500

Grant from Lake Tapps, WA on 12/16/2016

2013 Fiat 500

Verified customer (What's this?)
Verified employee purchase (What's this?)

Complete waste of my money. Even after being on the phone with tech for about 45 minutes none of my steering wheel controls work. Wish I wouldn't have purchased this.

Pros: I don't know if there are any pros to this seeing as it didn't work for my car what so ever. The Crutchfield Tech Support was nice but even after having them tell me the proper way to wire this up it still doesn't work.

Cons: Tons of wires to fit behind the deck. Terrible instructions from the factory. Throws codes up on my car (tpms sensors, airbag, fuel cut off) None of the steering wheel controls work even after spending almost an hour on the phone with tech support just to figure out what wires are what. Very cheesy looking modules. Be nice if it actually worked how it is supposed to.

Crutchfield response on 12/21/2016
Grant, we're sorry you're having issues with your interface. Our Tech Support team reached out to help get this working the way it should, or help return it for an exchange or refund.

A spider seb of wires but don't worry...

Venom from Austin, TX on 8/28/2016

2013 Fiat 500

Verified customer (What's this?)
Verified employee purchase (What's this?)

I'm not great with wiring and I was really apprehensive about getting this. But, the instructions help quite a bit. I will say this: If not for Crutchfield support, I never would have completed this project properly. There are a lot of wires and the instructions are so-so. Because of the instructions, I can't really give a 5 star rating. But, Crutchfield support walked me through after multiple calls. The wires are color coded and it's easy to connect properly. There are quite a few so slow and steady is the way to go. That's not necessarily the difficult part though (it is hard and rather tedious). Once you have the wires connected, setting up your particular system with the included boxes is somewhat confusing. Unfortunately, I had a bad box and had to return it and wait for a replacement. So, my dash looked like a tangled spider web. That's NOT Crutchfield's fault at all. I received my replacement, followed Crutchfield's support and everything is working. The steering wheel controls work, my OEM aux works so job completed! It's a bit buggy because sometimes things just hiccup but I'm ok with that and chalk it up to technology. Overall, I'm pleased with the ability to keep my steering wheel controls. Best part? Crutchfield support!!

Pros: Keeping Steering Wheel Controls Crutchfield Support

Cons: Tedious So-So instructions

Product Research

Features

Compatibility: The XSVI-6515-NAV radio replacement interface module allows you to replace the factory radio in a 2012-15 FIAT 500 vehicle (non-amplified/standard amplified system) with an aftermarket head unit.

Product Features: The XSVI-6515-NAV retains the factory R.A.P. (Retained Accessory Power) and OEM Bluetooth/USB/3.5mm audio, as well as provides accessory/illumination outputs, plus navigation outputs (parking brake/reverse/mute/VSS) for aftermarket head unit installation.

  • Accessory + Illumination Outputs: There is no 12-volt accessory wire in the factory harness, which requires the installer to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. The XSVI-6515-NAV is designed to provide a 12-volt, 10-amp switched accessory output (red wire), along with a illumination output (orange/white wire) to make installation simpler.
  • Navigation Outputs: The XSVI-6515-NAV provides essential wires required for aftermarket radios that have navigation. VSS (Vehicle Speed Sense), Reverse*, and Parking Brake wires are provided. This helps to cut down the installation time, since the installer does not have to look for these wires in the vehicle.
  • Retained Accessory Power (R.A.P.): The Retained Accessory Power (R.A.P.) function supplies power to the radio after the ignition is shut off until one of the front doors are opened. This function is retained by the XSVI-6515-NAV interface.
  • Retained OEM Bluetooth/USB/3.5mm Audio: The XSVI-6515-NAV includes an additional harness which allows you to retain your factory Bluetooth/USB/3.5mm audio sources. The harness features two sets of stereo RCA connectors which will plug into your aftermarket head unit's rear-panel auxiliary inputs.

* Note: If your Fiat 500 has a manual transmission, the reverse wire connection will have to be hardwired. This is because the reverse signal travels along the can bus, and connection to the interface is not possible.

OEM Steering Wheel Control Compatible (optional): The XSVI-6515-NAV interface features a right-angle 3.5mm connector that lets you keep your vehicle's OEM steering wheel controls via the optional Axxess Steering Wheel Control Interface (120ASWC1, sold separately).

Color Codes: Wiring up the XSVI-6515-NAV is like wiring up any other wire harness that would attach to an aftermarket radio's harness. The Metra/EIA wire code can be found on the back of the interface's package that will aid you in the wiring of your aftermarket radio The XSVI-6515-NAV interface contains the following wire leads.

Q
According to Metra, the newer revision of this harness has a standard USB port for upgrading/downgrading the firmware. Is this true? Because I don't want to spend $50 extra to fix the firmware to work with my Fiat (this is a known issue).
[ Nick  May 03, 2016 ]
1 answer
A
The current version of the harness we offer does not feature a USB port for firmware, no. A change such as that would warrant a new part number for the harness and a new item number for our inventory. I hope that helps! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5
