"Best TomTom to date."5.0 starson by TomS1222
Pros: Best screen resolution of any TomTom.On Par or even better than Garmin 3700 units Quick and precise Routing. Strong GPS signal. Excellent mounting system.Loud and crisp Speaker.
Fast Traffic system better than the Garmin Traffic with pop up ads.
Cons: Voice commands limited and somewhat confusing.
No Back button to get to the previous screen like Garmin has.
No SD or Micro SD slot
Summary: Overall the Pro's outweigh the Con's and TomTom has produced a High Quality product. The 4GB internal storage is plenty of space for US, Canada, Mexico and even Europe maps if you are so inclined. There really is no need for additional storage. This is after all a Navigation device and not an I-Pod. If you want to upload MP3's than do it on an MP3 player. For Maps and updates this unit has plenty of space. Up to Par with the Garmin 3790 unit which I also considered but personally I prefer the TomTom interface to Garmins. Besides the TomTom 2505tm is about $180.00 cheaper than the 3790lmt.
