The Becker Professional 50 LMU is a very well thought-Navi. I am many years of passionate Navigon driver. Unfortunately Navigon was indeed bought by Garmin. Now disappear Navigon devices from the market and you do not know yet whether Garmin is bringing similar Navis on the market. The Garmingeräte like to be me at all (too colorful) and the menu is not good (too complicated). I'd rather say times very very bad. Let alone the software. After much searching and trying I finally landed at Becker constructed very positively in the menu system and the Navigon comes closest. I opted for the Becker Professional 50 LMU because it holds the card updates in the purchase price and, above all because it has TMCPro (which has now become indispensable). With easy TMC will not get you far in NRW. Since the traffic messages only up to 20 minutes late coming to the device. That's when TMCPro different because everything is much faster and the error rate is also much lower. I highly recommend this Navi Recommend without hesitation and would buy me even again.
Update as of 9/6/2013
I am so far driven several thousand kilometers by Becker and may previously have had no experience really negative. The Navi is very stable. I had so far no crashes. Navteq Traffic works quite reliably, but unfortunately comes far ran to the Live Services by Navigon. But the TMC Pro reports are always accurate. However, information is missing for the downtown area and you can not receive support anywhere the sender TMC-Pro. Since then remains only the normal TMC. What is Becker significantly different from other Navis the search function to POIŽs. This is much easier when Becker. You can even enter search terms into words (similar to the Live service). My recommendation for this Navi still exists.
