If the battery fried, then you will need to replace the battery, this most likely happened if the charger was a higher amperage than the unit can handle. But in reality, anything could have broken, including capacitors on the chipset itself, which would require replacing the entire chipset inside the system. I would suggest bringing it to an electronics repair shop for a second opinion, but you may need to buy another unit.

My Tom Tom XL 325 wont hold a charge while left off

Hi, leaving the unit in the cradle exposed to the sun during hot days has been known to fry the battery causing loss of battery capacity. perhaps this could be your problem. I replaced the battery in my last GPS 4 times because of this before I analysed the problem. This will most likely be outlined in your user manual too. You might also compare the output capabilities between your blackberry and tomtom charger - it is entirely possible that you are starving the unit of a decent charge if the blackberry charger is not to the same current capacity as the tomtom charger.

My tom tom 300 won't charge in the car and seems to drain quickly when on the mount. Do the charging mounts go bad?

Every piece of equipment fails at one point or another. Wear and Tear. The problem may be the battery or the charger. Try charging it at a USB port of a computer if you have the cable.
As to draining, you can enact battery power saving features on your unit.
