According to all the reports I read in all media one of the MOST
stolen articles or incentives for car breakins is the GPS stuck to
the dash that and cellphones.
The last thing you want is "theftproof".
Crackheads will destroy your dash/interior to tear out desirable
resellable items.
Garmin sells Garmin Mobile XT and you can purchase a Bluetooth
linked receiver and pair it up to your 51v,that's what I have.
Both are removable and hide easily,plus if your into geocaching
or just trail walking you can carry it with you.
