I'm not sure this is the proper place for this issue. I have not been able to find a website dealing with this bid for help. I have 2 old models (ONE 3rd edition & XL330-S), both (over)due for replacement. My research indicates a replacement model would best come from the VIA line of TomToms. I want to compare the various available units, however, the COMPARE function on the TomTom product page doesn't appear to be working. I would appreciate any feedback that might be helpful to me in determining my next move. Thanks.
