During the Tabernas tour this week I tried out my Panasonic Toughbook for navigation purposes. First the hands up, I forgot the in car charger so only got a limited amount of time to try out the new receiver, 19 volt car chargers are a little thin on the ground in the desert! I also found Memory Map would not zoom, I am unsure if this is because it was a trial version or not although all other functions (waypoints, vehicle postion etc.) worked fine. The TB is great for OBD work on cars with the knocks and vibes but, it is too wieldy for use in the car for sat nav purposes, even when converted into tablet form. Looking at my options, I now realise I am way way behind with the current thinking on sat nav hard/software, so now looking for solutions. I have read through some of the threads on sat nav use on this forum but they seem to fade out around a year ago, so either there has been no further progress or people are happy with the offerings from last year or so? I like the idea and neatness of the double DIN in dash stereo/GPS units and gather they are Android based, I am thinking about one of the 7" offerings to get the larger screen, anyone using anything like this at the moment to run Topo maps, or can you get Garmin maps to run on an Android unit, I told you I was out of touch! I noticed on occasions last week that it was necessary to use a mobile satnav unit, some tracks splitting and causing confusion on the trail. Instead of jamming a convoy of cars into a dead end and then getting them to turn around, our 'routing techs' (nice one guys) took a walk with a hand held unit which helped clarify the route. I am quite happy to pay for an in dash unit and perhaps use my Android phone for out of car use but having a separate tablet would not get the use to justify the price, but could be proved wrong? So, talk to me. TIA regards Dave EDIT: The CB antenna was a little difficult to install, but Rodger was on hand to help with that.
