Hi I already own HTC Magic and pleased with its performance. Magic comes with built in GPS antenna. Does anyone know how to use the GPS functionality i.e. can one get a voice guidance on HTC magic (using google maps or install another program to get this functionality working) Also, I spoke to HTC support and according to them Magic can only support a max of 2gb MircoSD card. Has anyone tried a higher spec card? Thanks for your help. Londonuser.
