It could indeed potentially substitute for a map rather than having to find lots of tourist guides of small segments of Chernarus. Let's say you have the option by right-clicking the item in your inventory to "Turn On" and "Turn Off" the PDA. It'd be cool also to see the PDA require batteries and often warn you with a small buzz that the PDA is running out of battery; in order to get this there could be a chat message say "You feel a slight buzz signalling your PDA is almost out of battery." To insert a new battery, just drag the battery into the PDA and it should refill. I also came up with a small concept using your image (which I hope you don't mind) about maybe a "damaged variant" which can be found below: I decided to attempt making a version which was cracked, but also turned off. Again, as seen below;

This probably isn't going to be liked by anyone since it makes the whole scenario a lot more brutal but at the same time balances the crossbows effect. Basically, my idea is that the crossbows damage is reduced to a reasonable standard. However, if the crossbow bolt hits a target, it will lodge itself in there until the victim chooses to remove the bolt from his/her body. Obviously, if it hits them in the head or chest, it should be pretty much instant death. If you do not remove the bolt from your body, then after a while you will start to get an infection which would be seemingly realistic. Also, there should be messages which pop up saying "My [insert limb here] is in severe pain.", or something along those lines. Antibiotics and Painkillers should both remove the infection and obviously remove the pain. This is a default idea, but it makes the game much more realistic and eases off the crossbows current overpowered state, although makes it all the more deadly, and realistic.
