CatchnGrease, my understanding is that the 898 has no internal antenna and won’t give gps info without it, as is my case. If you only have one antenna it needs to stay with you so that unit will work.

I found one new online that is compatible and it’s on the way. Thanks for everyone’s help and input. Rickie, yours is headed back, be sure to look for the envelope inside, and thanks for your help. You’re the best.
