I know many of we be go crazy try to figure out which of the latest trucker gp unit be the best value . I have it down to two for many reason . I will go into why in another review when I make my final decision . no one have write anything -lrb- that be no user -rrb- about the Rand McNally tnd-710 . but I will because I just order it . I have be use this one -lrb- the Garmin dezl-560 lmt -rrb- lmt just mean include free lifetime map and traffic update . the lt will cost you to update the numap -lrb- that the mapping co -rrb- after 60 day from purchase . its worth get the LMT model for the lifetime update of map . do not get that confuse with software update to fix glitch ... they be always free . now about the lifetime traffic . well the receiver it come with that be build into the power cable be free because it throw up advertisement at you now and then . I hate advertisement ! I call Garmin which have excellent support as do rm and they say the non-ad power -lrb- the traffic receiver be build into the power cable -rrb- cable will cost a extra $ 120.00 and if you want premium traffic and construction service add $ 49.00 to that . WOW the only thing I can say good about that be its a one time fee . now to add traffic and speed camera update that $ 25.00 per year . let add this up . I pay $ 459.00 for the unit -lrb- 560lmt -rrb- on Amazon . $ 70.00 for accessory -lrb- Micro sd , Case , Windshield mount , Dash mount -rrb- $ 170.00 for traffic receiver power cord with prem software and $ 25.00 for the first year of camera warning . that $ 724.00 all together if you want all the bell and whistle as I always do . by the way all that ado about get add-free traffic ... it suck anyway . the traffic predictably be poor at best . just turn it off so you do not see the advertisement . save the $ 170.00 . maybe it will get better . its a 3rd part co so its hard to say . rm -lrb- Rand McNally -rrb- say it will offer a similar traffic receiver and service in June when there external antenna , case and other accessory come out . right now rm only offer map update for one year so its hard to say what the end cost of this unit will be . I want the best ! ... so I be spend alot to find out . DieselBoss be the only retailer I could find that be take the time to compare these two unit . check it out . http:\/\/www.dieselboss.com\/truck_gps_review_features.htm . the info be still come in about the garmin but I agree with what they say about the Garmin so far . . I buy the Garmin here on Amazon ... best price . I have own or use 5 other gpss to date . Garmin dezl 560lmt -lrb- same as lt but no lifetime traffic -rrb- pro ... \* start , route and re-route fast 10-30sec , no lockup yet \* -lrb- great route so far ... this be the most important feature about any TRUCK GPS . -rrb- \* show the post truck speed of most road next to you speed that turn red when you go over . \* -lrb- Garmin have a unbelievable database -rrb- every address I enter it have . this be not true of Google or even my co-pilot -lrb- pc-miler -rrb- . \* loud Speaker . \* quick access to brightness control . Easy snap-in mount -lrb- no usb plug to plug in every time which can break -rrb- \* Lane asst ... yea ... love that . \* lot of fun stuff and voice you can add from the garmin and 3rd party website . con ... \* 5 '' I want 7 '' . \* do not show the name of cross street as you pass they . \* you can not just pan & zoom on the nav map . you have to go to a special map screen . \* ETA do not adjust or work well at all ... but its so bad i be sure they will fix the software soon . my co-pilot ETA work perfectly . \* you can not show ETA and MTD -lrb- mile to destination -rrb- at the same time . Booo ... I want both ! . \* the graphic could be better . co-pilot be Sweet look . sound like I be work up Co-Pilot ... lol ... I be not . poor poor Truck map almost every time with Co-Pilot ... DON `` t buy . over View ... the hardware be rock solid , no freeze here and it re-route you fast if you miss a turn but I wish they have a 7 ' . \* the Software be very good for truck mapping and address thanks to garmin extensive datum base but need improvement on the stuff that not as important but convenient . I will update this as I learn , use and remember more . go on 3 day trip tomorrow . md-in-nj-dc-md let see what Rand McNally bring to the table with the tnd710 . I can not wait to get it .
