Thanks for the quick reply, Don Dee.
Until next summer or so I live in a student condo and park in the street, often a couple of blocks away. Hence no outlet, nor preheat.
Tested the OEM Omron remote while walking towards a parking house where the car charged. Like I suspected, it wouldn't connect until the very last corner. But I did indeed have GSM signal in situ, at the charging spot.
Unless I fork out an arm and a leg from my other end for der absolute spitzenklasse, all the GSM modules mostly act like simple, dumb on/off switches.
I have four realistic choices of heaters, times at least five types of GSM remote options. I'd like E85, but the government of No(r)way think hydrogen is better than PHEV is better than EV is better than biofuel/multifuel vehicles. A handfull of years ago, I converted my Toyota Starlet to E85. But, in secrecy, Statoil, with their 19'ish E85 pumps spread across Norway, secretly began removing all but two of them. BTW, did I mention that the gov control 2/3's of Statoil, aka big oil?
Therefore, sulphuric diesel will be my choice. http://www.ebay.com/itm/GSM-TERMO-remot ... ~B&vxp=mtr
