Out of all the head units purchased, I trust the Kenwood name. This doesn't use GPS maps, but with auto connection for both Apple and Android, that isn't an issue. I prefer it this way since the maps on the phone is always updated and you wouldn't have to spend any additional money in updating the maps on the head unit. This unit was installed in a 2007 GMC Yukon SLT. It's packed with features. Very easy to install. The price was roughly $150 cheaper than some of the other places selling the same unit. I highly recommend this product.
