Search the indicated locations to find all ten Gnomes.
1. Go to Papa B's Pawn Shop in Tenderloin to find it on a shelf inside.
2. Go to the Tidis corporation shipping facility, north of the Palace of Fine Arts. This is a front for the Brava crime syndicate. The Gnome is near the front gate, inside a doghouse.
3. Go a block north of Embarcadero Center, and enter the alleyway across from the park. Look for a rainbow-colored awning on a bus stop to know if you are going the right way. Go over the fence and climb the ladder to find a vent. Use the RC Jumper to enter the vent. Use the Blume control box inside before going to the rooftop. The ventilation duct will now be unlocked. Enter it to find the Gnome.
4. Look for a gang controlled lot with a small mobile home near the San Francisco to Oakland freeway. There is wheelbarrow full of dark liquid nearby that contains the Gnome.
5. Go to the HAUM Data Center. The block next to it has a parking lot and a small brick building with a mural of a unicorn on it. Reach the roof of this building to find the Gnome.
6. Go to the top level of the east block of the Transbay Center. Activate the RC Jumper (requires the "Enhanced Spring" ability) off the shorter hedge to access the walled-off area. The Gnome is found inside.
7. Go to Stache and Vine, near the Mission-Dolores Hackerspace. Across the street is a grey building. Reach the rooftop of the building to find the Gnome near the hot tub.
8. Search for the garden west of the Painted Ladies in San Francisco. Enter from the corner of Doobie Donuts, and go inside the alleyway. The Gnome can be found up the first set of stairs.
9. Go to the west end of the park near the San Francisco Museum of Modern Art. Go to the rooftop of Taqueria to find the Gnome.
10. Go to the tunnel between Lake Merritt and the Coliseum in Oakland. Climb up the small dock inside and use the ladder to find the Gnome.
All Key Data locations and solutions
Search the indicated locations and complete the listed tasks to collect all hidden Key Data and get the "Researcher" achievement. It is also needed to buy certain skills and upgrades. The Key Data locations are shown in-game and easy to find. Open the research app on your phone and press Y on a key data skill. It will show you the rough search area on the map, not always the exact location. You can use the Quadcopter and press the Right Analog-stick to scan the world for nearby collectibles. Figuring out the solutions to these puzzles is the harder part. Many of them require the RC Jumper or Quadcopter (RC Jumper is one of the first story unlocks; Quadcopter must be bought in Hacker HQ). One Key Data requires the "Environmental RC" skill (costs two research points). All the others can be found without the use of skill upgrades. You can reach all key data early in the game, after unlocking the research app. They are saved instantly when you collect them, and none are missable. You can also view which ones you have found in the research app.
This can be done in San Francisco. Near the "Dye Dude Kiosk" (marked on map) is a donut shop. During the day, you can find a man wearing a donut costume. He does not spawn at night, only by day during business hours. Buy the "APB: Suspect Located" and "Botnet Upgrade" skils (six research points required). Then, call the cops on the donut guy using the skill for them to come and arrest him and get the "Feeding Frenzy" achievement. Note: You may also want to take a picture of the donut guy before he gets arrested. He counts as a ScoutX Challenge for the "Got The Shutterbug" achievement.
Easy "Let Me Ride" achievement
You must first buy the "Vehicle Directional Hack" skill (costs two research points). This skill allows you to remote control vehicles. Just climb on the roof of a car and press LB + Y, then travel 200 meters to get the "Let Me Ride" achievement.
Easy "Miniroadtrip!" achievement
The Merengue can be bought from Total Motors car dealerships. It is a standard class vehicle and costs $43,125. After purchasing it, you can get it from the car dealer's garage or you use the "Car On Demand" app to have it delivered to you. Then, drive 4 km (2.5 miles) with this car to get the "Miniroadtrip!" achievement. Just drive it along a highway to quickly get it. You will get the achievement after stopping the vehicle, not while driving it.
Easy "Only God Can Judge Me" achievement
Fast travel to the "Nudle Vending Machine" in the south of Silicon Valley. It is marked on the map from the beginning. Buy a t-shirt for $5 from the vending machine to get the "Only God Can Judge Me" achievement.
Easy "Photobombed!" achievement
Simply walk around with your camera until someone makes a funny pose. The NPCs will do this very frequently when you aim the camera at them. This works well on sidewalks.
Easy "Smooth Felon" achievement
Go to the location shown in the video and start shooting at people until someone calls the cops. Kill the police to quickly raise your wanted level. At Level 5, drive through the underground parking garages. Close the doors behind you by pressing LB + A. Inside the last garage, lock the door by pressing LB + Y. When the door is powered down, nobody can enter. This effect runs out after a few seconds -- so you must quickly power it up and down again if cops are outside. If they did not see you driving into the garage (your radar turned yellow), this should be easy. After your radar turns yellow, you must stay out of sight for one minute. If this route does not work on the first try, just drive through all the parking garages again at a higher speed. Try to be out of sight by the time you reach the last garage.
Easy money
To get money quickly and early in the game, keep completing Driver San Francisco missions by simply driving passengers to their desired locations.
Gnome Outfit
You'll have to put in a lot of work to unlock the Gnome outfit, which is labeled as ?! in your wardrobe.
First, you must activate the first of two Gnome laptops. Look on Fisherman's Wharf to find a circular seafood restaurant. On the building's north side, find a duct and send the RC Jumper through the opening to reach a gnome and a laptop. Interact with those attractions to find a map pointing to gnome locations around the game world. There are also two 'X' marks, including one that corresponds to your current location.
Your next step is to find 10 gnomes, which are marked on the map and can be found in the approximate areas indicated below. You will need upgrades to access some of them.
Tenderloin: Pawn Shop - Sitting on the shelf at Papa B's Pawn Shop.
Tidis Warehouse - At the Tidis shipping facility, located north from the Palace of Fine Arts, take out the gangsters and dogs that patrol the yard, then check the doghouse positioned near the front gate.
Embarcadero Center: Health Store Roof - head one block north from Embarcadero Center, and follow an alleyway that extends from the park's northwest corner. It leads past a bus stop with rainbow awning. Vault the fence, climb a ladder to some scaffold, then drop your RC jumper into the vent at your feet. Access the Blume control box, then climb to the building's roof. Open the ventilation duct that you should have unlocked with the Jumper, and use that Jumper once again to follow the vents to the waiting gnome.
Soma Freeway Entrance - Look for the on-ramp that accesses the freeway where it crosses from San Francisco to Oakland. Beneath that ramp, you'll find a homeless camp guarded by gang members. Drive a box truck, van, or a lift to the fence along the back of that area. Then send an RC Jumper over the fence to collect the waiting gnome (it is resting in a wheelbarrow).
Haum Data Center - The block next to the HAUM Data Center beneath the Bay Bridge (between SF and Oakland) contains a parking lot and a small brick building (there's a mural of a unicorn on it). Using a construction lift or other raised platform, reach the roof of this building to find a Gnome (and some other toys).
Transbay Center - On the top level of the East block of the Transbay Center, there's a large hedge square in the center of the rooftop park. Using the Enhanced Spring skill (or a tall truck), launch your RC jumper off the shorter hedge next to these and into the walled-off area. Inside is a deeply unsettling tableau and another Gnome.
Rooftop Hot Tub - Across the street from the Stache and Vine near the Mission-Dolores Hackerspace is a grey building with a rooftop patio. This area can be reached either by climbing the storage shed and latticework on the West wall or by using a construction lift found in a nearby gang-occupied yard. Look near the hot tub to find the gnome.
Garden of Peace & Love - A block to the west of the Painted Ladies is small communal garden (with naked hippies). Enter it from the corner where Doobie Donuts is located and climb the first set of stairs on your right inside the alleyway. At the top of the stairs you'll find another gnome.
SF Moma - On the west end of the park across from the SF MOMA, use the construction lift to reach the top of the taqueria. There is a gnome around the corner of the rooftop.
Oakland: Aquaduct - Between Lake Merrit and the Coliseum runs a tunnel that boats can pass through. In the center of this tunnel is a small dock area - climb ashore and up the ladder to find this gnome resting on a lawn chair.
After finding the gnomes, you need to seek out the area that corresponds to the other 'X' you saw on the map. Make your way to the north end of a park located next to the WKZ station. Check in the tent near the area's northwest corner to obtain the new clothes that are your reward for the extended scavenger hunt.
Infinite money
Late in the game's campaign, the "An Eye For Eye" main operation will become available, with "A Real Dog Fight" sub-mission as its fifth main component. During the "A Real Dog Fight" sub-mission, you will go down a large freight elevator. When it reaches the proper floor, proceed to the indicated in-game mission area with the double doors, and hack the camera to see a room full of people with a man and woman standing next to each other giving a speech. The man is Pablo The Skinner. Point the camera at him and hack him to get approximately $18,000. Then, simply display your phone, select "Game Options", choose "Reload Last Checkpoint", and repeat the process as many times as desired. When the checkpoint loads, you can run into the back left corner of the elevator and hack Pablo The Skinner to do this even quicker. You can get over $1 million in less than an hour using this glitch. Note: This glitch was performed on an unpatched version of the game. It will probably eventually get patched. To avoid not being able to use this exploit, either do not install new patches before using this exploit or delete the patches. You can avoid patches being installed by disconnecting from the internet until you are ready for the game to install new patches.
