I bought a mustang dominator 870 hdlm. A unit arrived within a week but it was a Titan! I TRIED to call but kept getting a message saying "they were busy with other customers" EVERY time i called! They directed me to their web site to email them..i sent several. They FINALLY emailed me back to tell me that THEY had researched it and the Titan is better and i would be better off with that one. I called and emailed again and they FINALLY wrote back saying there were several OTHERS that they would exchange for which were better for a FIRST? TIME? USER. How would THEY even know if i were or not!? I have written them AGAIN to see if they will finally send me WHAT I ORDERED! If you are even considering buying from these people...i WOULDNT! I picture some dude sitting behind a lap top in a garage with a pile of GPS units to get rid of and he is REALLY good at making a believable web site...and there i was..looking for a good gps with all the right features... . We will see what happens. In the mean time, BUYER BEWARE!
