Just FYI for everyone, Rocky Road now has these, and very inexpensive compared to the prices on the Airflow site. But, as of last week when I was talikng to RR, still no fix for the antenna. The online help from RR actaully called Airflow while I was on still nothing.
I have been thinking of one but then there is the whole "is this really usefull" question. Not sure how many people ford rivers but this is only one little step. The fuses under the hood would need to be waterproofed, the electronis, everything...big job
