At 73, and despite being a so-called computer-wiz during my work life, I just can't be enthused about 21st century beam-me-up-Scotty technology. I use my cell-phone to make telephone calls and a few other things that don't require a magnifying glass or midget fingers. And all during my computer-centric life from the early 1980s, I would find a way to make use of the technology in some sort of DIY project that makes life easier.So I have a 1995 (orphaned) Isuzu Trooper, dubbed by my mechanic as a vehicle that was meant to be indestructible, at 190,000 miles passing smog as if new, using no oil and with prospects for another 100,000 miles of mild or occasional maintenance expense. I wanted to bring the 20th century vehicle into the 21st century. So I embarked on a plan to add MP3 and FLAC play, GPS, voice-recognition and voice-navigation, rear-view and front-view cameras, and entertainment redundancy to the old Trooper. An Android tablet would be the brain-center and means of integrating everything.The dashboard needed a semi-permanent mount for the device. I settled on placing it in front of the dashboard center vent. If it were too big, it might fall off and pose a hazard. Too small, and its inconvenience might detract from its advantages. Some people use their cell-phones for some of the aspects cited for my project, but I wanted something I could leave on the dashboard.I settled on this 7" Vankyo S7 tablet, after exploring the specs for other 7" devices and larger tablets. It had to at least be quad-core. It needed to have Android 9, but not Android 10 -- given the other aspects of the project whose apps would not work with I-phone 10 or Android 10.0 -- at least not yet. It had to have GPS. It had to have Wi-Fi, and it had to have Bluetooth. The fact that it provides digital FM radio was a very sweet and wonderful extra.The Android works with my 1995 OEM car receiver through an FM-transmitter which plays MP3 and works with Bluetooth, providing USB charging as well. It will also work with a Bluetooth device inserted in the receiver's cassette-tape deck. Either way, sound quality is marvelous even though the Vankyo's own speakers leave something to be desired.This little dandy is very reliable and as fast as I'd want. Of course, I might want it a tad faster when booting up, but the bootup time is just about 1+ minute, or the time to warm up the engine. After that, I select my Rolling Stones album from Google Music Play, tell Google Maps where I want to go and press "Start", then switching to the rear-view camera as I back out of the garage or any parking place.I don't need it to have a SIM card or a cell subscription, as long as I can connect to the home LAN via Wi-Fi occasionally for software updates or new Google maps. It's only practical to avoid a separate monthly subscription fee for a 25-year-old vehicle, don't you think? Even so, I've got a cellphone, which can also be integrated with my retro-fit components to allow for hands-free calling.So -- the Vankyo S7 was stellar, at least for my particular needs. Mounting it to the dash has been another ongoing problem-solving project, leaning toward a hybrid construction using an OHLPRO suction device and foam-core art-board laminates inserted in the center dashboard vent louvres. Rock-solid, even at this exploratory stage!Maybe I can't get Scotty to beam me up. But I can go anywhere in my shuttle-craft, told where to turn by the onboard computer, and I can scan for Klingon warships before they cloak themselves. Even for that -- I have "night vision"! All the while, with three different sources of music entertainment at my fingertips and the ability to switch from one to the other without taking my eyes off the road . . . . er . . . . I mean "galaxy". . . . take my eyes off the galaxy . . . .
