Works with 998C SI unit
I purchased this to replace the original antenna that came with my 998C SI unit. The antenna stopped working after two years.
This new antenna required a software update on the 998C, but worked fine afterwards. It's installed on my boat and is now working fine.
The system acquires a 3D Fix quality signal within seconds of powering up. It accurately shows my position on the map.
I'd recommend this product for others to purchase.
