Wich Gps To Choose

hi me again,i have a 560 dezl garmin 5",wich is good so far,it didnt take to a low bridge yet,butheres an example,i parked at newark,nj,everydaymy trip is to coneticut,i now know i take I-95 north al the way until i get to Ct,of corse,depending to wich place or part of Ct i go,but my garmin afteri pass the GWB keeps telling me to take many exits on my way to CT,it seems to be many low bridges on his route/maps,wich they are not on the road at all,on my way back the problem is worst,taking I-95 south to newark,nj,the second problem is that instead of go straight to a place,it makes me to go all round to place i go,wich results in time and fuel,delays etc, my question to you is,should i buy a rand mcnally or a cobra trucking gps? i have two friends that have cobra,they said that they had them for about a year,and so far they are good,besides that i hear rand mcnally freeze,and other than that what do you think about copilot app for android,i been thinkin of that long time ago,but that trucking app is $150,waiting for your advice and sugestions,thanks.
