    Icon14 CANBUS and installing new HU

    I have a 2013 Fiat 500 Abarth (with Beats factory audio) into which I am planning to install a Clarion NZ503 NAV HU and Alpine amps/speakers.

    When I talked to the service manager at the local Fiat dealer and told her what I was planning, her response was "fine, but your odometer is going to start blinking after you install the new head unit".

    Research shows the Fiats are on a Chysler CANBUS system, pins 3 & 4 of the factory harness connector, data signal, puts the system on a internal computer management bus, if one disappears or changes -- blinking odometer.

    That lead me down a path of doing a"PROXI realignment", to reset the CAN BUS, which, for DIY, requires a modified DLM327 OBD interface and something like MULTIECUSCAN, which is apparently available in EMEA only (the OBD interfaces are available on eBay UK).

    I haven't yet asked the dealer service manager if they can realign the CAN BUS for me, that may be a better option.

    My question is -- since I will be using a "AXXESS XSVI-6515-NAV - NAV Interfaces - 2012-UP FIAT 500 RAP Accessory Retention Harness" which is a "CAN" interface, is all this even necessary? It looks like the AXXESS interface provides the required signal on the CAN BUS connections however, since it is going to change from the factory HU, I am thinking it's still going to throw a CAN code which means -- blinking odometer.

    Any info or advice appreciated.

    The current Axxess interface for that vehicle is AX-ADXSVI-FT1. These are reverse engineered to work with the factory computers and not throw an error code. The dealer is wrong.

    Thanks. This is the one I ordered that hopefully will work. I guess I will find out when I install it
