im getting a used radio from ebay.
and it seems like i have to have some sort of anti theft
code for the radio unit and this person whos selling me
a radio doesnt have one. according to few ebay postings,
i might be able to get a code from dealer with VIN number,
but they might charge me. so i was wondering if there is any
way i can look it up somewhere? : / or .... if anybody knows
how to deactivate the alarm? im just so fed up with all the
maintenance i have to keep up with.........................
its just too much money. all happened with my spoiled boss'
daughter who kicked the radio (monitor broken), messing around
me when i was getting outta parking lot (hit the curve bottom
penal completly destroyed..) just need simple easy CHEAP way
to get all of these done................ i would really appreciate it if anybody has any ideas.......................
oh also, i dont know what happened .. but my dash board ,
the plastic cover (for the mileage and speeding needle part) has really weird stuff on. it seems like the
old owner used wrong cleaning product on dash board , it looks
like all oily stuff on plastic i dont know how exactly explain
but if anything could clean the plastic part up...........
please suggest any products if you know ... thanks !
