This is a Sync 3 APIM. You can tell that it's Sync 3 due to it's non-rectangular shape, large heatsink fins, and the two blue connectors on the left side. Sync 3 APIMs have changed throughout the years, so keep reading to learn more...
What you should know:
-- Sync 3 APIMs do not have a built in GPS antenna, you have to use an external GPS antenna
on both Navigation & Non-Navigation units.
-- Sync 3 Non-Navigation units need an external GPS antenna as well for syncing clocks to GPS time & giving a detailed location to emergency services in the result of an accident.
-- Sync 3 Non-Navigation & Navigation units are completely different modules and there's no real way to tell the difference just from looking at them. They share the same type of motherboard, but use completely different daughter boards which have either 8GB of storage on the non-navigation module, or 32GB on the US Maps Navigation module.
-- If your Sync 3 Navigation module has software of v3.2 or older, you can update it to have more recent maps.
-- You can put any Sync 3 setup into a vehicle that came from the factory with Sync 2.
