Sorry I just need to reconfirm, because currently 4 type of touchscreen from Nokia. N97 (can use garmin), Nokia 5800xm (can use garmin, my wife using it), Nokia 5530xm (confirm no gps and no 3g) and Nokia 5230 (With 3g and I see the spec it come with A-GPS from Nokia homepage). So I wondering A-GPS is a build in GPS or really need to get BT gps. Because I plan to replace my hp with Nokia 5230 if can use garmin too. Thanks.
