I purchased a Q3 GPS system on ebay and the seller called and told me there were issues with my GPS so they said they would send me a replacement model known as the W3. Although it is a previous model they told me it was just like the Q3 except it does not come with the remote control and the designs are a little different. But when it comes to the software everything is the same. Plus it is a MP3 player if I put a SD memory card in it. Does anyone have the Nextar W3 or Q3 GPS systems? Are they good?
