The first representative was TomTom. What has extremely displeased me, the TMC receiver was in the charging cable. This "nub" is very disturbing and prevented even the thick cable for a designed for permanent use "hidden" laying of the connecting cable.
The Navi-SW TomTom uses maps from Tele Atlas. Whether it is because of their cards or on the Navi-SW of TomTom, I do not know, but so totally unusable POI search I have ever experienced. We use just on longer holidays by car, the POI search very extensive (shopping, accommodation, food and drink, tourist destinations, etc.), but the TomTom is totally unusable.
Therefore, I have taken from TomTom far distance.
The second representative was Garmin, however, some time ago, and here the TMC receiver were designed as "nub" in the charging cable. It was a knock-out criterion, what I have regretted since the Garmin POI management to galaxies is better than TomTom. Garmin uses map data from NAVTEQ.
The third representative was quite current Becker. Also Becker relies on maps from NAVTEQ. At the newer devices with built-in TMC receiver and magnetic holder I'm almost as happy with the POI management, as shown less clearly with the Garmin, however, are the POIs. In addition, the connecting cable is for magnetic holder quite thick and inflexible, so Becker has fallen by the wayside.
Currently I have now devices from Garmin - nüvi 56LMT and 66LMT - in use. These - and other newer navigation systems from Garmin - have a built-in TMC (Pro) receiver and the charger cable is designed as a TMC antenna. It's exactly as thin as "normal" charging cable. The TMC reception works well and m. W. exclusively with original automotive cables Garmin cheap foreign products have no antenna reception, even if stated otherwise. I could move the original cable in three vehicles for problems permanently.
About "Garmin Express" can be made by PC completely easy firmware, and the maps are brought up to date.
Sure, there are things here that I do not think is very practical and that could be better:
- Even if the Navi is completely off, it activates when it receives power (when you turn the ignition it comes with the appropriate connection always on).
- One can not enter a tolerance threshold is switched on pace warning.
- The distance to the next maneuver only in small numbers (. Eg 200 m) progress bar in split screen (and otherwise) is specified, this would be a fast to be detected better (additional?).
-All These points are better in the Medion GoPal Navi-SW.
This Garmin Navis are no frills, as meaningless games, picture viewer, FM transmitter, etc.
After the next major holiday with the Navi I will add my experience.
