Hi guys, Still new here, so bear with me on the questions that may have been asked a million times before. (have tried the search function but drawing a blank) Currently have a 2001 Lupo GTi with factory cassette and Cd player, really want a double din sat nav, have seen a couple of MFD sat nav units out of a bora but was wondering if these are any good, and how much I should expect to pay. How accurate is the nav control? or are there better units out there, any recommendations would be appreciated. Been looking into the RNS310 too but not sure if they fit either. Basically, a budget dash fitted Nav unit as hate the Tom tom that falls off the windscreen all the time. Thanks
