Summary: Very easy to use, updating the maps is a needed at this point but is very easy to do also. The operating system updates the same was also, a small sd card is needed to do any of these. Connection to the head unit was direct and simple.
Summary: FINALLY GOT IT INSTALLED (BEEN TO COLD TO INSTALL OUT DOORS), BUT IT WOULD CONNECT THEN LOOSE NAVIGATION. TRIED TO INSTALL UPDATED SOFTWARE USING A 8G SD CARD, THAT DIDN'T WORK SO I USED A 256M SD CARD AND IT WORKED THE FIRST TIME. SEEMS TO WORKING FINE NOW, NOW I NEED TO TRY UPDATING THE MAPS.
Summary: Kna g510 work excellent. I have a kenwood DDX7015 receiver that was installed in my ford f150. They work great together. Waited a long time to put these units together. The GPS display are beyond words . Clear & precise. Only one question, what the different between 2D & 3D viewing on the GPS unit?
Summary: I installed this in my 2005 BMW M3. It works as advertised but the maps were somewhat outdated. Replacement maps from Garmin was almost $90, which I wasn't expecting. Aside from that, fantastic product.
Summary: I have an older Kenwood DDX6000 series DVD in dash receiver and it connected perfectly and worked just fine the GPS receiver (antenna) cord was just long enough to install. I recommend the back window for the best point-of-view to get a GPS signal.
Summary: I've owned this for a few years already, there may be a newer model out, but beware of this device. It doesn't have the basic function of displaying speed limits. Map updates are very, very expensive.
