Avimap
Functions well on short, low speed trips. Downloads are a serious pain. Wifi can be super high speed or home link, it drops either way. When it gets hot, it can do a sector in 10 minutes. Wish I knew how to keep it warmed up as I have worked the download thing hard. One cross country requires 8-12 sectionals. Do not wait until pre-flight!
