Garmin 220, time to buy a new one??

[David76]

Hello, a question from Spain... my Astro 220 is 4 years old and it started to give me problems. Twice in one month the Astro recognize my three collars and give me their position with gps and vhf communication, but after two or three minutes, the communication fell down at the same time with the three collars and it can´t obtain the position of the collars again, only "?", but the collars are ok. If I reset and update the Astro and the collars, everything it´s ok during 2-3 minutes... but after that... "?" again... The first time It happened I reset and updated, and the problem seemed to be resolved, but some days after that, the problem came back and by now I can´t resolve it.

My question is the following... is there any solution I could do to resolve it? Would be better to buy a new one and/or repair my old Astro? and change my Astro by a refurbished one? what do you think about??
