You might just wana upgrade to a newer system either Garmin or TomTom they both have new/ cheap models might drop only $90-150. My parents got the new TomTom for only $89. Costco and other warehouse areas are selling them under $200. With your Garmin being like this it might just need to be updated or something could be up with its circuits. You could also look up Ebay they have everything you need, all the accessories are very cheap between 2-10 bux each.I have an old Garmin GPS 12 which has always worked well, but now it won't work right. It won't give coordinates.
