I'm looking at adding a portable GPS unit to my coach. Would like to be able to pull it out easily for use in our towed vehicle on occasion. Would appreciate feed back on manufacturers, models, location of portable antenna, etc.
Any GPS made within the last five years will not need an external antenna on a fiberglass RV, nor your car. My two most recent Nuvi Garmins are easily transferable between vehicles, I prefer a glued on dash mount that the GPS slides and locks into, rather than the suction cup mount. The mounts of my last 5 Garmins are interchangeable, any GPS goes in any of my cars or RV. "Ram" makes mounts that allow you to securely mount most Garmins with bikes, motorcycles, boats, planes, etc. for extra versatility.
Map software updates do not need to be done every year, a waste of money. Most roads don't change, you might miss a new housing developments address, it not that often a problem, the GPS still works like it did when new many years later. Newest POI's (Point Of Interest) are not a big concern to me, again the majority stay the same for years. A smart phone as a GPS is becoming popular, my concern would be discharging the phone's battery, and losing the ability to use the phone as a phone. You should buy a mount to use it like a dedicated GPS.
I actually prefer some of the older Garmins that will play hundreds of mp3s through your car stereo, I recently bought a $120 newly refurbished 755T from Amazon that I like a lot for road use in the BF (because the 03 BF has a single CD player stereo), it came with a no charge Garmin map update. Load a whole bunch of music into it to play through the vehicle stereo, convenient, but apparently not a big demand feature, so MP3 players have been dropped from the newest Garmins. Transfers easily between vehicles, and small to carry for exploring on foot. Not the disaster to lose like a smart phone would be, costs less than a tank of gas. I find Garmins more intuitive to use than Tomtoms, Magellans, and off brands in N America. In Europe, Tomtoms have the reputation of better maps.
