Wahoo units do decent turn-by-turn navigation, in that you can generate a course in RWGPS, download it and it'll navigate you with on screen turn directions. The Wahoo units lack a color screen and I don't think the on-screen direction method is as nice as what Garmin offers, which is in color and easy to read.
As this is a resurrected thread the answer to Junglelands post is that the Wahoo units have a nice zoom feature that increases text size, but reduces the number of data fields that are shown as it does that. Other and larger devices (that cost more) have larger text due to the increased screen size. Wahoo Roam is $380 and is the same size essentially as a Garmin Edge 830 ($399). Then the Edge Explore ($250) increases screen size even more to near the size of the 1030 ($500-$600). The larger the screen, the easier to see the text and map info. The Explore is a nice unit just doesn't have all the performance features (power meter, most fitness functions) etc... is more oriented to somebody doing bike tours.
