On Saturday 3/12 I set off on an ECO Range Test Tour visiting Bassman. The objective was to purposely emulate his daily commute home (in the mid 60's in terms of miles). Before pulling out of my garage I entered his address in the foothills (around Angels Camp, CA) into the NAV without any trouble. I had also done some pre-planning checking Google Maps and elevations (1,500 feet). I had never been to Angels Camp, nor was I familiar with the (significant) terrain along the route, and I knew ahead of time that I might encounter a very low state of charge.
The Angels Camp, CA area in the foothills consist of very steep terrain and twisty mountain roads along ridges with few chances for "ridge jumping" (interconnecting roads).
I will postpone further the more detailed report of Range, SOC, etc. But after a significant hill climb the (polite female) NAV voice informed me
. This happened as the Range Estimate (42) crossed below DTD (Distance to Destination) on the NAV. So far so good; no worries, I had 43 miles to go, but had reached a significant elevation, and was doing just fine with the Average Energy Economy (3.6mpk). But here goes the NAV system problem: As I approached a significant turn-off ... no notification from the NAV. Being unfamiliar with the area I was “blissfully” unaware and merrily continued on the designated route, with 10 miles DTD, when another 5 miles later the (polite female) NAV voice informed meYou might not be able to reach destination. Press button to check.
( I have a recording of this. ) I seem to also recall the first instance of this “warning” included words to the effect that “these roads will be shown in blue” (which they now were – on the unreachable ridge) and “follow all traffic regulations” (or something like that). At this point -- based on the miles from origin -- I should have reached my destination, but now realized I was miles beyond the turn off, and the NAV display was indicating my destination on an apparently unreachable ridge only 3.7 miles away. I had kept an eye on the NAV’s DTD as well as the Range along the way, but really had no indication of a problem (just a few miles earlier DTD had been the (approximate) expected 10 miles).The route to your destination includes roads through incomplete map areas. Voice guidance will not be provided in these areas.
( There was no cell-phone coverage … it took almost a mile to find a safe turn-around, and I then backtracked 6 miles to the nearest town (and the DTD on the NAV increased to more than 20 miles at one point). With 2 SOC bars and “low battery charge” message, and 10 (real unknown terrain) miles to go, I “grabbed” a 120V outside outlet at a gas station and called Bassman from the station’s Mini-Mart landline … the “rest of the story” some other time. )
Suggestion to Nissan (NAVTeq?): If ...
… would you PLEASE TELL ME THAT AHEAD OF TIME !!! i.e. when I enter the destination in the NAV ! So that I am aware of a potential problem ?! And not trust the NAV ! ... when I am closer to my Destination ... or when the NAV might be silent while I should be taking significant turn-offs ?!The route to your destination includes roads through incomplete map areas.

TIA ! (Thanks-In-Arrears )
