Hi all, wanted to share my experience having an aftermarket remote start system and a subwoofer installed in my '20 G70. I have been very happy with both systems so far, and the local car audio shop that installed both did a great job.

Remote start system:
The first gen G70 does not have a remote start built into the keyfob. The only option for stock is to sign up for Connected Services and use the app. Here are my pain points that made me wanted to move to something aftermarket:
  • Hit or miss if the app actually works. Feels like 50% of the time it would be a successful start, the other half failed.
  • Long time for commands to be sent to the vehicle. I believe it's built on 3G, and it took ages at times to load.
  • Far and away the price. $240 a year to be able to start my car quickly made it not worth it, and I intend to keep my vehicle for a long time.
I went to the shop and asked for the best system they had. I wanted a two way, physical remote for command confirmation, long range, and just plain worked every time. In addition, if it is important to you and you like having phone control, the system is compatible with DroneMobile which is Compustar's (RS manufacturer for my system) mobile app control. My quote was for $600 regular price for the system and install, but they had a promo for $100 off if you purchased during their black friday sale. If you want to replicate this system in your vehicle, DroneMobile says I have the Compustar C900s module (brain for the starter) and the Compustar FMX remote. Antenna is the ANT-2WFMX. If you go to the best shop in your area, they should take care of you and you probably won't need that info, but I enjoy knowing everything about my vehicle so I thought I would provide it.

Experience getting the install and helpful info:
I had an initial issue after getting my starter put in, where the remote would confirm that a start was successful, but the car did not start. The command would be sent, but the car would not crank long enough for the motor to turn over. This wasn't an issue with a warm engine, but these Nebraska winters can be brutal and I needed it to work every time on freezing days. The first time I went back to the shop, they showed me how to program the tachometer so the starter would know when it was a good start. After sitting overnight in the cold, I started the car and programmed the tach using the sequence provided by the shop, but this did not fix the issue. I went back a second time, and the sales guy told me that they instead did something called a "simulated crank" which I believe replicated how the push-button start commands the starter motor to turn over. This completely fixed the issue and the car remote starts without fail, every time.

The remote fob is my preferred method to start the car. I can unlock and lock doors and the start the car, and it also has a trunk button as well. I'm not sure if it's just my power trunk in particular (it's very finnicky to work at times) but the remote starter can only pop the trunk, it doesn't initiate the power trunk system. No sweat for me, the actual key fob works just fine for that purpose.

The antenna is mounted to the windshield. The shop elected to install mine right next to my dashcam, just right of the LKA camera system by the rear view mirror. Mine also has a nice, bright blue light that flashes for security. I like the look better, and will cover up the stock red light on the dash soon.

DroneMobile (mobile app to start the car):
If you like the convenience of starting your car with your phone, DroneMobile is a fantastic app that I believe is exclusive to Compustar installs. It solves a lot of the issues with the Connected Services app and it does everything better. The only downside is it is subscription based. They have varying tiers based on the features you want, and different pricing depending on how long you purchase (month by month, 1 year, 3 years, 5 years). It is built on 4G so the system talking to the car is way faster. You can remote start, lock and unlock, track the vehicle, and even use Siri on your phone to say "Siri, start my car". Other perks include monitoring battery voltage, checking the interior temperature of your car, and adding other drivers to the app if you share the car so they can also remote start. If you find these features valuable, it's a great app. I am electing not to purchase a subscription and just use the physical fob provided.

Subwoofer install:
Unlike the remote start, I sourced all of the components for my install. I wanted to design a system that would blend seamlessly into the excellent Lexicon system. In addition, I also wanted something small so I can use the trunk space still. Happy to report this setup sounds amazing without being overly boomy or loud. Here's what I went with:
  • Sony XS-GSW101 10" sub (purchased on Facebook from another shop that was closing out old stock, purchased new in box for $50 (!)
  • Rockford Fosgate R500X1D (have owned this amp for a while, grabbed from another install in my previous vehicle.)
  • Audio Control LC2i line out convertor (went with a higher budget LOC to be able to use their AccuBass bass restoration feature, and accept the higher wattage speaker signal from the amplified Lexicon system)
  • Audio Control ACR-1 remote bass knob (I had the RF knob, but it felt cheap and plasticy. This knob is way better to use.)
  • KnuKonceptz 8 Gauge OFC sub wiring kit ($50 on Amazon)
  • Atrend 10" sealed box (wanted a tighter sound and to preserve trunk space. Purchased from car audio shop as I didn't have a box and didn't want to build one.) I think you can find this on Amazon if you want the exact box I got.
The system sounds amazing. I listen to almost exclusively hip-hop, and this system is perfect for my needs. The Sony cone is at 4-ohm resistance, and at 4 ohms the amp supplies 300 watts RMS vs the 500 watts they advertise for 2-ohm configs. If you feel you're missing the deep low ends in your system, you can't go wrong with a setup similar to this. In addition, because of the low profile box I got, I can fit all of my detailing supplies in the trunk still (shop vac, tool bag for chemicals and tools, vacuum hose, towels, etc.)

For the bass knob, I asked the shop to use double sided tape instead of drilling holes into the dash. The remote is to the right under the steering column. My shop was awesome and turned off the light from my remote for me, I would 100% ask for them to do this for you if your remote has a light.

Something to keep in mind:
If your line output convertor uses signal sensing turn on like mine does, I would probably recommend you ask the shop to run a remote wire instead. The G70 sends power to the speakers for a while even after locking the car (about 10 minutes in my experience.) In addition, if you unlock the car, walk up to it with the proximity mirror feature turned on, anything to activate electronics, the sub amp and the LOC will power up. I'm not super worried about battery drain with this, but for peace of mind I would just do it the right way instead.

Thanks for reading, and I hope this info is helpful for others. If you have any questions, I'm happy to answer them.

I had a shop do it (because I didn’t want to figure out the colors) so I couldn’t tell you. You might try doing a low frequency test tone to isolate the sub wires.
