Hi Its really a great unit for the price. I bought mine 2 weeks ago and its going good. have not had any problems with it. The touch screen is good or if you wanna call it responsive - I dint realise any delays in the functioning of the unit. USB drive is the qickest one to pick up data after the radio. if you go buy the unit - Susan's voice is text to speech (TTS) i.e. it says street names. It took some time for me to get it. However, if i look back it was common sense - it says TTS next to her name from where one can select different voices. (duh) DJKOR - mate, I tried to update the software from the link - but it did not run on the GPS - I tried everything (in my capacity) I even bought a new card - it reads it but does not automatically act like the original one. The original SD car shows 2 folders (GPS LOG and R15 maps for PNA - this has iGo8 folder in it and other data) Let me know what else can i do.
