Summary: Works very well! I do service and repair work and have to drive to multiple unknown destinations every day. This unit gets me there every time. I like the fact that the screen is not cluttered with icons that I don't care about. The unit also tells you how efficiently you are driving, which is a must for my business. I would highly recommend this product.
Summary: ok usable gps add-on unit ,not many interest points ,what i dont like is map view - looks like garmin 10 years ago ,graphics are not impressive at all ,highway exit views are much better ,overall not bad but i wouldn't be paying more than $250 for it ,for more than 250 i would add another 80$ and buy new model avic-u250
Summary: Very poor resolution (400 x 272) while compared to the in-dash (800 x 400) of the Pioneer compatible AHV-P8400. Screen looks like its and old VGA monitor, with choppy images. Just doesn't make sense as Pioneer points this as the compatible product and image is so disappointing when you turn on the GPS. The aplication itself is also quite poor - very limited functionality, specially if compared to stand alone models in the same price range. Last, maps are REALLY outdated.
Summary: Works fairly decent as a navigation unit, but it's way overpriced for what you get. I'd expect a unit this price to come with lifetime updates and also announce street names. I bought this thinking it would be more advanced than my old Garmin Nuvi 850 - I was wrong. The Garmin outperforms on all fronts.
