Summary: This unit works well for me. I am pleased with the sound quality, the workmanship and the features. However, there is one item of concern. If you want to add on a bluetooth device and satellite adapter later, you should know you can only add one or the other.
Summary: This is a great radio the only things keeping me from giving it 5 stars> Very slow start up 1-2 minutes. No direct connection for Ipod you have to buy a separate adapter. The USB uses only flash drives so you can not use a portable hard drive with the system.
Summary: Although I did LOVE my REN MyGig, it was lacking something major for me, NAVIGATION! I tried to get the same MyGig with navigation, but at this price, I couldn't help but try the Kenwood. First, the navigation. It works SO much better than my Magellan GPS model.
Summary: I bought this for my wife for Christmas since she liked my pioneer Avic D-3. It isn't as good as the Pioneer, but it does what it says it can. The maps are fairly accurate, with a few (why the heck is it making us turn here in the middle of this field) moments, but overall an average GPS system...
Summary: I picked the 5140 over the 6140 because I don't need bluetooth, besides that the units are exactly identical. Had Best Buy install the unit, they did a superb job for much less than what some of the local audio shops were quoting me.
Summary: Pros: - Excellent GPS - The backlight is fine. - AM/FM Radio is OK. - Plays CDs - Plays DVDs Cons: - Bluetooth is an add-on (6140 has it integrated, 5140 makes you buy a seperate add-on) - XM is an add-on (More money, you need 2 special items to get this working, receiver and the connector.
