What exactly is the MyGIG NTG4 REZ car stereo system?

MyGIG is Harman's previous-generation car audio and SatNav system that came before the modern Uconnect branding. The NTG4 REZ is a touchscreen navigation auto radio with a built-in hard drive for music storage and an anti-theft security mechanism requiring a 4-digit keycode. It was standard in many 2008-2016 Chrysler, Dodge, Jeep, and RAM vehicles. Think of it as the predecessor to today's Uconnect systems - same great functionality, just an older generation.

Which vehicles came with the MyGIG NTG4 REZ system?

You'll find the MyGIG NTG4 REZ in vehicles like the 2011-2016 Jeep Grand Cherokee, 2011-2015 Dodge Durango, 2013-2016 RAM 1500/2500/3500 trucks, 2011-2014 Chrysler 300, and 2012-2014 Dodge Charger. It was typically included in higher trim levels that had the navigation package.

How can I tell if I have a MyGIG REZ versus another model?

Look for the part number on your radio's label - it'll start with P05064247 or P05064248. The serial number begins with T00AM, which confirms it's made by Harman. The REZ model has a 6.5-inch touchscreen and includes the navigation hard drive. If your screen boots up showing 'MyGIG' instead of 'Uconnect', you've got the older generation system.

Why does my MyGIG radio need an unlock code after disconnecting the battery?

It's an anti-theft feature built into the radio. When power is cut - whether from battery replacement, radio removal, or electrical work - the MyGIG locks itself automatically. This prevents thieves from just unplugging your radio and using it elsewhere. Once locked, you need to enter the original 4-digit code that's tied to your specific radio's serial number.

Is the MyGIG NTG4 REZ code different from newer Uconnect codes?

Yes, even though both are made by Harman, they use different unlock algorithms. MyGIG systems (2008-2016) have their own code structure, while newer Uconnect radios (2017+) use updated security. The good news? Our service handles both generations automatically - just enter your serial number and we'll generate the correct code for your specific radio.

MyGIG vs Modern Uconnect: What's The Difference?

A Bit of History

Back in the late 2000s, Chrysler partnered with Harman to create MyGIG - their first serious attempt at a modern infotainment system. It was actually pretty advanced for its time with the hard drive storage and touchscreen navigation.

Around 2013-2014, they started transitioning to the "Uconnect" branding, which is what you see in newer vehicles today. Same manufacturer (Harman), but updated software and hardware. Think of MyGIG as the grandfather of today's Uconnect systems.

Which Vehicles Have MyGIG NTG4 REZ?

The MyGIG NTG4 REZ was Harman's premium navigation system before they switched to the Uconnect branding we know today. If you've got a Chrysler, Dodge, Jeep, or RAM from around 2008-2016 with a touchscreen and navigation, there's a good chance you're looking at a MyGIG system.

Here's what makes it interesting: MyGIG radios have a built-in hard drive (usually 20GB or 30GB) where you can store your music collection. Pretty cool for the time! The NTG4 generation brought better graphics and faster processing compared to the earlier NTG1 and NTG2 models.
