I recently got a good deal on an OEM Navigation System for my 2016 Hyundai Elantra Limited. I knew I would need to purchase a GPS antenna, which I was able to do for very cheap through Amazon.

The majority of the cables are the same between my original factory radio and the new GPS unit, but there are 3 wires in the stereo wiring harness that do not match up.

Before I start splicing and soldering, I wanted to ask if anyone has done this upgrade? Does anyone have any experience (good or bad) with this project?

Is there a better GPS option available for my make/model car?

I originally went with the OEM GPS system because I thought I could avoid a wiring harness compatibility issue, but it looks like I may have to splice at least one wiring module.

I've noticed that map updates are quite expensive through Hyundai (I've been able to find an SD card on eBay for a good deal).

Any advice or direction on this will be greatly appreciated and hopefully will save others some time should they choose to go this direction.

Thank you!
