I have use Garmin for year and like it . so when it come time to buy another GPS , I want to go with Garmin . so on Christmas day -lrb- when I get it -rrb- , you could not even use it until you `` register '' it on Garmin.com . yet of course that web site be totally screw up . it be not just mind-bogglingly slow , but then it keep time out when you finally do get through . I like the fact that when I request my username it send it to I at my email address , but when I request my password , it say that it do have my email address . Huh ? you just send a message to it ! totally nut . and then it do not come with a wall charger , but then when you try to download thing , it have to be charge ! so you have to take it out to the car and let the car run for a while as the unit charge , then bring it back in and try again to get software download to it . nice . then I buy the unit that show mileage , etc. , and you plug it into the OBD II port . yet they do not even tell you be the OBD II port be on you car ! Crazy . I think that if you be go to sell product , you should support it . I be disgusted . if I can not get this stupid thing work shortly I be return it .
