I just recently purchased a TomTom VIA 1525M and after watching a youtube video, I found the SD card. But I can not see how one would be able to pop it out. I am not sure if it is a doable feature. When I view the system "about", it shows that I have 1.76 GB internal memory available. It also shows an option for "Format memory card". So I am a tad bit confused on this issue - do or do I not have a slot for an external SD memory card ?? And if so, How do I insert it etc ?? Thank you.
