OEMs can't be jacked. Nor do you have to take out the damn thing every time u get out the car, or put it on when you get into the car.
OEMs has integrated functions such as using the NAV screen to display AC, vehicle health/diagnostics, and music info.
OEMs nav have way stronger satellite signal as its antenna is housed in a sharkfin on the exterior of the vehicle.
Did I mention portable GPS looks ugly and ghetto as hell? Most mount points are not safe and are within the vicinity of the airbag shall they explode, which will fly that thing into your head.
The only thing a portable GPS have over an OEM GPS is price. There shouldn't be even be a comparison, it is like comparing a Civic to a Mercedes, both will serve the intended purpose of the product, but someone is willing to pay more for the extras. There is simply no point to compare them, different level of products intended for different market segments. People buying $200 portables are not gonna buy $2000 OEM navs.
