its really worth paying the 2k to get the 610...i have the same unit and very happy with it...used it in singapore recently and was very accurate (using malsing maps) ...it has a bluetooth interface for your mobile phone and use handsfree, dial up on the touch screen, voice activated dialling etc. (works well with nokia)..it has a MP3 player included..can also have voice e books while u drive...the large screen is very useful..the only drawback is the volume level..find it a bit low even on max..highly recommended unit..i got it for RM2000 about a 2 months ago..should be able to get it less than 1.9k now..prices are dropping...good luck
